Application Notes
•
Stopping Time
The Baldor Dynamic Brake can stop the motor faster than the motor will start (at full volts). However, this could damage the
motor. It is best that the motor should not stop any faster than the motor starts. A dynamic brake should never be set to stop a
load faster than the load starts. Stopping the motor too fast or too frequently can cause motor overheating and possible failure.
•
Motor Sizing
Each stop with a dynamic brake should be treated as a start for calculating duty cycle and for sizing the motor. The brake
does not have a duty cycle limit.
•
Holding Brake
A solid state brake is not a substitute for a mechanical holding brake.
•
Motor Types
The Multipurpose Brake has been designed to operate on 3-phase induction motors.
•
Brake Sizing
Use the motor FLA and operating voltage to size the brake. All Baldor Multipurpose Brakes can be used on high inertia loads.
Extended stopping times are available for use on high inertia loads.
WARNING:
A DC injection brake is not a replacement for a mechanical or safety brake for emergency stopping
