Constant Speed AC Motors & Gear Motors

Constant Speed AC Motors & Gear Motors

AC motors and gear motors include single-phase motors used with a single-phase AC power supply and three-phase motors used with a three-phase AC 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 AC power supply.

  • 1 W (1/750 HP) up to 3 HP
  • Parallel Shaft, Right-Angle Solid and Hollow Shaft or Round Shaft (no Gear)
  • Single-Phase or Three-Phase VAC

Speed Control AC Motors & Gear Motors

Speed Control AC Motors & Gear Motors

AC speed control motors and gear motors allow for the motor speed to be changed. By combining an AC motor with a dedicated control circuit speed changes can be performed. A broad lineup of AC motors & gear motors that can easily be used for speed control is available.

  • 6 W (1/125 HP) up to 3 HP
  • Closed Loop or Inverter/ VFD
  • Single-Phase or Three-Phase VAC

Features and Types of AC Gear Motors

Constant speed motors come in various types as shown below. Select from a wide range of products depending on the application, required functions, output, etc.

Easy Operation

AC motors and gear motors include single-phase motors used with a single-phase AC power supply and three-phase motors used with a three-phase AC 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 AC 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.

Induction Motors

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

AC Induction Motors

Reversible Motors

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

AC Reversible Motors


Electromagnetic Brake Type (Induction or Reversible Motor)

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

Electromagnetic Brake Type

Washdown Motors

Geared AC motors of excellent watertight, dust-resistant structure. These AC motors conform to the IEC standard IP67 or IP65.

Washdown Motors


Torque Motors

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

Clutch & Brake 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.

Clutch & Brake Motors


Low-Speed Synchronous Motors

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

Speed Control AC Motors

AC speed control motors employ a closed-loop control system by utilizing feedback from the built-in tachogenerator.
