 The rated torque and starting torque values of reversible motors are based on models without a built-in friction brake.
 All safety certifications are obtained based on the model number indicated on the motor nameplate.
 This product is equipped with an internal thermal protector (self-reset type).
When the motor overheats, the protector operates automatically and stops the motor to prevent damage.
 Once the motor temperature has sufficiently decreased, it will automatically reset and restart.
For inspection or servicing, always ensure the power is turned off beforehand.
 For “-A” models with a 110V specification, please refer to the actual motor nameplate for the correct capacitor rating.

※ Additional machining can be specified only when selecting shaft types GN or GU.

Allowable Torque When a Gearhead Is Mounted

  • Please purchase gearheads and mid-gearheads either by specifying additional machining for the motor or from the standalone product page (AC Motor Gearhead EA Series).
  • When the additional machining code GH is specified, the gear ratio is entered in the box (□) within the model number.
  • Combinations shown in the yellow cells (  )indicate that the output rotation direction is opposite to that of the motor. All other combinations have the same rotation direction.
  • The rotational speed is a reference value calculated by dividing the motor’s synchronous speed (50 Hz: 1500 r/min, 60 Hz: 1800 r/min) by the gear ratio.
  • The actual rotational speed decreases by approximately 2–20% from the listed value depending on the load.
  • If a greater gear ratio than those listed in the table is required, please add a mid-gearhead with a gear ratio of 10 between the motor and the gearhead.
    In this case, the allowable torque is 20 N·m.

Product Features
1. Basic Structure and Operating Concept
A reversible motor is equipped with a friction brake on the rear side of the motor body and is designed for applications requiring frequent forward/reverse switching.
A spring-loaded damper constantly applies pressure to the rotating brake disc, maintaining a consistent level of friction at all times.

The primary functions of the friction brake are as follows:
① Improving instantaneous forward/reverse performance through frictional load
② Reducing overrun
③ Maintaining a constant holding torque
 (approximately 10% of the rated torque)

2. Holding Torque and Overrun Values of the Friction Brake
①Please refer to the specification table for holding torque and overrun values.
②These values may vary depending on operating conditions such as duration of rotation and ambient temperature.
③During initial operation, the actual torque may be slightly lower than the listed values, so caution is required.

3. Motor Characteristics
Reversible motors use a capacitor-start system similar to induction motors and exhibit nearly identical torque characteristics.
However, to enhance instantaneous forward/reverse switching performance, the starting torque is designed to be higher than that of standard induction motors.
