Model 126-4B: Base-Mounted Type (Clutch, Brake, and Motor)

This model features a standard three-phase motor directly connected to the input shaft of the 125-series electromagnetic clutch/brake unit, allowing the output shaft to be repeatedly started and stopped without stopping the motor. It enables high-frequency intermittent operation compared to simply turning the motor on and off. It is designed for base mounting.

The 0.2 kW and 0.4 kW motors are totally enclosed motors with external fans that comply with JIS C 4210, while motors rated at 0.75 kW or higher comply with JIS C 4213.
The motor's input power supply is three-phase AC 200 V / 50 Hz, or AC 200 V or AC 220 V / 60 Hz.
If you require special voltages (5-power-supply specifications) or different pole counts for general-purpose motors, please contact us.
The dynamic friction torque Td is the value at a relative speed of 100 min⁻¹. Additionally, depending on the initial torque characteristics, a break-in period may be required.
