Abstract
The utility model relates to a servo motor with an external brake device. The motor comprises a motor main body and the brake device. The motor main body is provided with an output shaft, and an end of the output shaft extends to the external of the motor main body. The brake device is fixed on an outer side of the motor main body. The brake device comprises a connecting shaft sleeve, a friction plate fixedly disposed on the motor main body, and an electromagnetic mechanism. The connecting shaft sleeve is fixedly disposed on an end of the output shaft. The friction plate is in a circular shape and is coaxially disposed with the output shaft. The electromagnetic mechanism comprises an annular armature. The armature is coaxially disposed with the output shaft and is fixedly connected with the output shaft. When the motor is powered on, the armature separates from the friction plate under the action of the electromagnetic mechanism. When the motor is not powered on, the armature is tightly abutted against the friction plate. The servo motor is advantaged by being arranged out of a motor, so maintenance and adjustment are convenient.
