BMS (NHF) Flange-Mounted Type
We have integrated an internally mounted, non-excitation brake and power supply into the motor without altering its standard dimensions. When power is applied, the motor shaft rotates; when the power is cut off, the motor shaft stops. This is effective for emergency braking and similar applications. Additionally, a release lever allows the brake to be manually released even while the motor is in a held state. This is a flange-mounted type.

- The 0.2 kW and 0.4 kW motors are totally enclosed, externally ventilated motors compliant with JIS C 4210, while motors rated at 0.75 kW or higher are compliant with JIS C 4213. (Manufactured by Hitachi Industrial Equipment Systems Co., Ltd.)
- The motor's input power supply is three-phase AC 200 V/50 Hz, or AC 200 V and AC 220 V/60 Hz.
- For the permissible braking frequency of the brake motor, please refer to the page on design verification. Since the specific frequency varies depending on the load conditions, please verify it using the selection calculations.
