Stepping motors are used to achieve precise positioning via digital control. The motor operates by accurately synchronizing with the pulse signal output from the controller to the driver. Stepping Motors, with their ability to produce high torque at low speed while minimizing vibration, are ideal for applications requiring quick positioning over a short distance.

The high-torque type motor adopts a new technology and design. A high-torque motor produces approximately 1.2 ~ 1.5 times higher torque than a conventional stepping motor of the same size.

This motor combines high torque and a compact size. Five frame sizes are available: 0.79 in. (20mm), 1.10 in. (28mm), 1.38 in. (35mm), 1.65 in. (42mm) and 2.22 in. (56.4mm). Each specification provides torque equivalent to a motor of the next larger frame size, supporting high-torque operation even in the high-speed range.

For example, high torque type PK246PB [motor frame size 1.65 in. (42mm)] has the same holding torque as the standard type PK266-01B [motor frame size 2.22 in. (56.4mm)]. This means a smaller size motor will maintain the same torque. This allows for downsized and lightweight equipment.

The terminal box type motor conforms to the IP65 standard of ingress protection against water and dust.

The terminal box type motor conforms to the IP65 standard of ingress protection against water and dust.

On average the PV Series provides 1.5 times higher torque than a standard stepping motor. By utilizing a larger rotor diameter, larger magnets can be used to significantly increase the output torque.

4. Cooling Modules

Today's comfortable life and society is supported by advanced control systems, which may present many heat sources. To operate these devices 24 hours a day, 365 days a year, the devices require appropriate heat designs and heat measures. Oriental Motor offers a wide range of heat measure products centered on cooling fans to meet these requirements.

One method of cooling heat sources and enclosures is air cooling, which utilizes the air around us. One device that can use this air is a cooling fan, which uses the power of a motor to spin a propeller or impeller to blow air. Oriental Motor provides three types of fans: axial flow fans, centrifugal blowers and cross flow fans, using different air-blowing systems.

Oriental Motor offers a wide variety of axial flow fans from large air flow, high static pressure series to compact AC or DC input series to 100,000 hour long life series.

Cross flow fans deliver a wide, uniform air flow.

Centrifugal blowers are optimal for spot cooling and for air flow through a duct, which provide directional air flow by maximizing static pressure.

Cooling modules are integrated with an axial flow fan, finger guard and filter. These modules help reduce equipment problems caused by ingress of dust or water, while saving installation and replacement costs.

AC motors are used generally as a power source for automated equipment, because these motors can be operated easily by connecting the motors directly to an AC power supply. Oriental Motor offers standard AC motors incorporating various operating functions. A standard AC motor supports various applications by using with a brake pack or speed control circuit product, and combining with other mechanical components such as a gearhead or linear head.

Oriental Motor offers a wide variety of standard AC motors in frame sizes ranging from 1.65 inch (42 mm) to 4.09 inch (104 mm) square with output power of 1 W (1/750 HP) to 200 W (1/4 HP). There are two basic types of AC motors: standard induction motors that run continuously and reversible motors that allow for bi-directional operation. AC motors with additional functionality are also available. These types of motors include: electromagnetic brake motors to hold loads in a power-off situation; clutch & brake motors for quick starts and stops; synchronous motors and low-speed synchronous motors for a fixed speed in synchronization with the power frequency; watertight motors for applications were the motor is splashed or washed with water and torque motors for tension control and winding applications.

Many of Oriental Motor's AC motors conform to UL/CSA/EN standards and apply the CE Marking in accordance with the low voltage directives. AC motors are available in power supply voltages that meet the requirements of North America, Asia and Europe.

AC motors include single-Phase motors used with a single-phase power supply and three-phase motors used with a three-phase power supply. A single-phase motor can be operated by simply connecting it to a single-phase power supply via the supplied capacitor. A three-phase motor does not require a capacitor. All you need is to connect the motor directly to a three-phase power supply.

The Power Supply Frequency Determines the Speed The basic speed (synchronous speed) of a standard AC motor is determined by the power supply frequency and the number of poles. Many of our standard AC motors have four poles, so their synchronous speed is as follows:

• 50 Hz: 1500 r/min
• 60 Hz: 1800 r/min

The actual speed varies according to the load torque.

With our motors, the speed roughly falls within the following ranges at a load torque equivalent to the rated torque:

• 50 Hz: 1200 to 1300 r/min
• 60 Hz: 1450 to 1600 r/min

The rated speed of our standard AC motors are set within the above ranges and shown in each motor's specifications. To calculate a more accurate machine speed, use the rated speed as a reference. the power supply frequency varies from region to region. In the case of automated equipment used in different regions, change the gear ratio of the gearhead or take the appropriate measure to obtain the desired speed.

These motors can be easily operated from an AC power supply. Single-phase and three-phase motors are available.

Oriental Motor offers a wide range of AC induction motors. Induction motors are optimal for uni-directional continuous operation such as a conveyor system. Capacitor-run, single-phase and three-phase motors are available. Lead wire type, terminal box type and conduit box type motors are available depending upon how the power source and the motor are connected.

Generating a greater starting torque and having a built-in friction brake, these single-phase motors allow for instantaneous switching of rotation direction.

Oriental Motor offers a wide range of AC reversible motors. Reversible Motors are capacitor-run, single-phase motors. The outward appearance is the same as that of induction motors. These motors are suited for applications where the motor must frequently switch direction.

These motors adopt a power off activated type electromagnetic brake to hold the load in position when the power is cut off.

Oriental Motor offers a wide range of AC electromagnetic brake motors. Electromagnetic brake motors feature a power off activated electromagnetic brake for load holding.

Geared motors of excellent watertight, dust-resistant structure. These motors conform to the IEC standard IP67.

The FPW Series are geared motors which conform to the IEC standard IP67 (Recognized by UL). They are ideal for applications where they are splashed with water. These watertight motors are available in 25 W (1/30 HP), 40 W (1/19 HP), 60 W (1/12 HP) and 90 W (1/8 HP) models.

A special rotor is used to provide rotation at a fixed speed in synchronization with the power supply frequency.

Synchronous motors provide rotation at a fixed speed in synchronization with the frequency of the power source, regardless of fluctuation of the load or line voltage. Synchronous speed is 1800 r/min at 60 Hz. It is possible to decrease motor rotation by attaching a gearhead. Synchronous motors are available in frame sizes from 2.36 in. (60 mm) up to 3.54 in. (90 mm) and feature output powers of 4 W (1/190 HP) up to 25 W (1/30 HP). Synchronous motors run on a single-phase 115 VAC power supply.

Uses the same stator and rotor as stepping motors. The motor offers superb starting, stopping and reversing characteristics as well as synchronous operation.

Low-speed synchronous motors provide highly precise speed regulation, low-speed rotation and quick bi-directional rotation. The basic construction of low-speed synchronous motors is the same as that of stepping motors. Since they can be driven by an AC power supply, they are sometimes called AC stepping motors.

Equipped with an electromagnetic clutch and brake at the motor output shaft. High frequency starting and stopping is possible while the motor is operating.

This compact, precision motor is equipped with an internal clutch and brake mechanism for use with a gearhead. This combination makes it the ideal motor for applications involving frequent START/STOP operation, positioning, indexing, jogging and incremental feeding. CB motors have a 3.54 in. (90 mm) frame size and come in output powers of 40, 60, 90 W (1/19, 1/12 and 1/8 HP).

A special rotor is used to provide large starting torque and sloping characteristics (torque is highest at zero speed and decreases steadily with increasing speed). The torque can be changed by changing the applied voltage.

Torque motors are designed to provide high starting torque and sloping characteristics (torque is highest at zero speed and decreases steadily with increasing speed), and operate over a wide speed range. They also provide stable operation, especially in the low speed range or under a locked rotor condition. Torque motors are available in frame sizes from 2.36 in. (60 mm) up to 3.54 in. (90 mm) and support single-phase 110/115 VAC and single-phase 220/230 VAC power supplies.
