| PARALLEL BRAKES
Description: Brake has its own set of leads and can be operated independent of the motor.
Advantages: Can be operated independently of the motor and can thus be performance controlled very accurately. Able to stay disengaged even when the motor os operating at low torque conditions.
Disadvantages: Generally less holding/stopping torque then series brakes. Depending on the hook-up, back EMF from the motor can delay the brake engagement time after the motor power has been removed.
General information: Brakes are spring-set and fail-safe indicating they mechanically engage if power is removed. Brake leads are teflon insulated per MIL-W-1878, Type "E" with gauge dependent on voltage and current requirements. Brakes are mounted to the rear of the motor and are enclosed/protected by an aluminum cover chemicallly filmed per MIL-C-5541. |
SERIES BRAKES
Description: Brakes leads are wired internally in series with the motor.
Advantages: Have potential for more stopping/holding torque than parallel brakes. Generally have quicker engagement/response times than parallel brakes once the power is removed from the motor.
Disadvantages: Cannot be operated independant of motor. Can have difficulty staying disengaged when motor is operating at low torque conditions. Not good for low voltage applications.
General Information: Brakes are spring-set and fail-safe indicating they mechanically engage if power is removed. Brakes are mounted to the rear of the motor and are enclosed/protected by an aluminum cover chemically filmed per MIL-C-5541. |
