Special Features
- The brake motors are simple & rugged & so easy for maintenance.
- No separate DC supply is required as the rectifier is provided which gives the required DC voltage for energisation of the brake.
- The rectifier is mounted inside the main terminal box so no separate terminal box required.
-
General guidelines for selection of suitable Brake Model
- The Brakes are rated by torque & selection of suitable model can be made by calculating the required torque, rating of the brake & then matching it with static torque.
- Torque (Nm) = 9550 x (KW / RPM) x Safety Factor (SF)
- Where kW-Kilowatts of motor
- RPM-Speed of motor
- SF-Safety Factor depending on type of prime mover & load.
- For electric motor, SF = 2 to 3
- For diesel engine, SF = 4 to 5
- For compressor, SF = 5 to 6.
