Product Description:

The A3.SM.000-62DY is a compact synchronous servo motor produced by KEB within the SM Synchronous Servo Motors series. It serves as a low-inertia rotary actuator, converting electrical energy into controlled mechanical motion for positioning tasks in automated machinery such as pick-and-place axes and small packaging stations. The frame conforms to a 63 mm hole circle, allowing direct flange mounting on compact drives without additional brackets. Its 9 mm shaft extends 20 mm to accept standard couplings, while a 40 mm pilot diameter centers the motor for repeatable alignment.

During continuous operation, the windings are energized from a 230 V supply and draw a nominal 2.0 A, producing 0.6 Nm of torque at a rated speed of 6000 rpm. Under those conditions, the mechanical output equals 375 W, a level suited for light-duty servo axes. The 6.1 Ω phase resistance regulates current flow, while the 3.9 mH inductance helps smooth current ripple from the drive. These electrical characteristics support stable torque production as the controller adjusts motor current in response to changing speed and load demands.

During acceleration, the drive may supply up to 10.8 A, enabling a peak torque of 3.2 Nm for short bursts such as indexing or rapid deceleration. If motion stops with current applied, the motor can hold 0.65 Nm at stall without overheating, helping prevent vertical loads from drifting. The back electromotive force gradient of 28.3 V/1000 rpm supports drive selection because the required voltage rises linearly with speed. This constant can be used with the motor’s electrical characteristics to confirm that the selected inverter provides adequate voltage headroom for regeneration and field weakening. Peak current and torque should be reserved for brief dynamic events rather than continuous operation, while the stall value applies when the shaft remains stationary under an energized holding load.
