Product Description:
The 63.G6/K.135 is a synchronous servo motor engineered by KEB for the SM Synchronous Servo Motors series. It is designed for closed-loop positioning and speed control in industrial automation. In machinery such as indexing tables, packaging lines, and gantry axes, the motor converts drive-controller current into precise rotary motion. Its feedback capability allows the connected drive to correct changes in position and speed while the machine follows tightly regulated motion profiles.
This model delivers a continuous stall torque of 22.0 Nm, which is the steady force it can supply without thermal overload when the shaft is locked. During acceleration or while holding a stationary load, the rotor can produce a peak torque of 36 Nm. This temporary torque capacity provides additional force for demanding starts and brief load increases. A rated speed of 5000 rpm supports rapid movement in applications with short cycle times. The motor has a frame size of 63, which provides the mounting envelope and magnetic stack volume needed for its torque range. The base assembly weighs 21.5 kg without the brake, an important consideration when calculating machine support requirements and axis inertia.
An integrated brake locks the shaft when its control power is removed, helping prevent an attached load from moving while the axis is inactive. The enclosure has an IP54 protection rating, which limits dust intrusion and protects the motor against splashing water from any direction. This protection is suitable for industrial locations where airborne particles or occasional liquid exposure may occur. Torque is transmitted through a shaft with a feather key, providing positive engagement with pulleys, gearboxes, or rigid couplings. The keyed connection helps prevent the coupled component from slipping when the motor experiences load reversals or repeated acceleration cycles.
