Product Description:
The 53.SM.200-34B0 is a synchronous servo motor produced by KEB within the SM Synchronous Servo Motors series. This frame-size 53 unit is intended for closed-loop axis control in industrial automation, where torque linearity and position feedback are required to coordinate conveyors, gantries, or packaging stations. It interfaces with KEB drives as a rotary actuator, transforming electrical power from the drive into mechanical shaft motion.
At its rated speed of 3000 rpm, the motor can deliver a continuous stall torque of 13.5 Nm, giving machine builders a fixed torque-to-speed point for sizing gear ratios or direct couplings. The stator has a nominal voltage of 330 V for use in 400 V-class systems, and the motor can also operate from a 560 V DC bus when paired with a compatible regenerative inverter. Rotor position is measured by a 2-pole resolver SSBH-15-E-5, which provides analog sine-cosine feedback to the controller for commutation and closed-loop servo control. Thermal regulation relies on self-cooling; heat is transferred through the aluminum housing to the ambient air, so no external blower or liquid circuit is required. The elongated three-phase housing also provides additional surface area for heat dissipation.
Mechanical integration uses a B5 IFT5 flange pattern that mates with standard gearheads and mounting plates. The smooth steel shaft is supplied with a feather key for positive torque transmission, and the assembly has an enclosure protection rating of IP54, which protects against harmful dust ingress and splashing water. The motor has a total mass of 11.2 kg, which affects inertia calculations and lifting requirements during installation. Because the motor is supplied without a brake, static holding force must be provided by drive current or an external mechanical lock, allowing rapid axis release when the application requires it.
