arner Electric’s MBFB series of Electrically Released Brake Modules are designed for brake
only applications when mounted to the back of a NEMA C-face double shaft motor.
The fail safe brake engages when power goes off.
Mounting Instructions
Step 1: Mounting the Brake to a Motor
The brake module (20) can be mounted
directly to the motor as follows:
A. Insert a key in the motor shaft keyway. Prick
punch the end of the motor shaft keyway to
prevent the key from sliding out.
B. A set collar is provided in the EM-210
mounting accessory to prevent the key from
sliding out. Slide the set collar against the
motor bearing and tighten the set screw
securely. (See Figure 1)
C. Align the motor shaft and key with the mating
shaft hole and key slot in the brake module.
D. Slide the module onto the motor shaft so the
module surface is snug against the motor face.
NOTE: Brake Module should slide freely
onto shaft and fit flush with motor c-face.
E. Secure the brake module in the motor C-face
with the four (4) long hex head capscrews.
Suggested torque for capscrews is 30-35 lb.ft.

Failure to follow these instructions may result
in product damage, equipment damage, and
serious or fatal injury of personnel.
If brake is to be applied with the
brake output shaft in a vertical condition
Warner Electric's application engineering
should evaluate application.
The term “fail safe” describes a brake that
engages automatically when its full power is
shut off for whatever reason. The term, as
applied to brakes, designates a mode of
operation, not a guarantee of safety for the
equipment on which the brake is mounted
and for personnel who are near it.
