BMS (NHB) Base Mount Type

三木プーリのBMS-NHBタイプ無励磁作動形ブレーキ付きモータ製品画像（フェイルセーフ対応・安全保持・産業用駆動源）

We have integrated an electrically excited brake and a power supply unit into the motor without altering the dimensions of the standard motor. 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, the brake can be manually released even while engaged using the release lever. This is a base-mount 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.
