These motors have built in thermal protectors: If a motor overheats the thermal protector opens and the motor stops. When the motor temperature drops to the
rated level, the thermal protector closes and the motor restarts.

Enter the gear ratio in the box □. Colored background indicates the output shaft rotate in the same direction as the motor shaft.
The speed is calculated based on the synchronous speed (50 Hz: 1500rpm; 60Hz: 1800 rpm) by the gear ratio.
Higher gear ratio (>200) can be achieved by adding a middle gearbox (10:1 only). Using Middle Gearbox limits Max.torque to3Nm (30kg.cm)
