How to Install a Brake on a Motor?
In order to realize functions such as emergency braking, power-off retention, and safety protection of stepper motors, a brake is usually installed on the motor. STEPPERONLINE provides customers with two optional brakes: permanent magnet brakes and non-excitation brakes.
Because permanent magnet brakes are complicated to install, they are not sold separately. Therefore, this article introduces the installation method using non-excited brakes as an example.
Specifications of non-excited brakes
All brakes sold by our company are power-off brakes. That is, when the power is off, the brake is applied and the motor shaft cannot rotate freely and maintain its current position.

As shown in the picture above, the following requirements need to be met when installing the brake:
● The motor must have a rear shaft, and the diameter must comply with the installation dimensions and be milled flat (D-CUT)
● The rear end cover of the motor has reserved holes for brake installation.
