Servo motor with and without brake

Servo motors usually have a braking function, which generally refers to the electromagnetic mechanical holding brake device at the rear end of the servo motor. It is usually installed at the rear end of the motor and brakes the motor and locks the motor spindle through the brake pads acting on the motor spindle during operation.

So the brake of the servo motor, namely the holding brake and holding brake, functions similarly to the handbrake of a car. So the brake is used to lock the position when the motor stops, preventing the motor from moving (due to external forces).

Servo motors generally do not brake through electromagnetic mechanical brake devices, which generally serve as an emergency protection function. For example, if there is a sudden power outage during operation and the driver cannot provide braking function, the electromagnetic brake will work, locking the motor shaft to avoid accidents.

1. Different application scenarios
Servo motors with brakes are generally used in vertical or inclined motion situations, and do not require brakes for horizontal motion. Generally speaking, Fuji servo motors with brakes are used in applications where the motor is not allowed to move on its own after power failure. For example, a vertical axis without self-locking function.

2. Different prices
In general, servo motors with brakes are more expensive than those without brakes. Whether or not to have brakes is not directly related to the power of the motor, so motors with brakes are more expensive than motors without brakes.

3. Different functions
The servo motor with brake is designed to protect the motor when it stops. The servo motor should not be subjected to axial force. When the motor is not powered on, it will be affected by external forces and affect the system. If it is not powered on, brake should be applied. Otherwise, brake is not necessary.
