BRAND: MONTROLI
TYPE: BRAKE MOTOR
MODEL: BMA SERIES
1. Description
- MONTROLI BMA Series 3-phase brake motors are made to IEC & GB Standards, also up to the international latest design technology. The power range of brake motor is from 0.25kw~3kw in 4 frame sizes from 71~100L to satisfy variable applications.
2. Motor Features
- Aluminium alloy whole casing with heat sink design for better cooling effect.
- Corrosive-resistant & vermin resistant.
- Weather-proof,hose-proof & dust-proof.
- Precise dynamic balance adjustment and adopts high quality bearings to ensure smooth and silent torque.
- The brake is made of wearable material without asbestor. It can provide the dry friction break torque.
- DC transformer is not required. The AC connection is more safe & reliable.
- Powerful brake effect, high break efficiency & frequency.
- When a preset sealing device of the output shaft is connected with the variator or reducer,the sealing performance is more safe & reliable.
- Assembled with manual release handle easy for installing or adjusting.
- The brake plate & rotary shaft are connected with the steel key tooth, it can bear the strong impact during the brake process.
- There is a superior interchangability between the IEC Standard & IM mounted forms.
