Product Description:

KEB manufactures the B3.SM.HF0-64J0 in the SM Synchronous Servo Motors series. This three-phase permanent-magnet unit is deployed as an actuator inside automated pick-and-place heads, indexing tables, and compact extruders. It works with a matched KEB drive to translate command currents into tightly regulated shaft movement, providing the dynamic response expected in modern production cells. The motor’s mechanical profile allows direct flange mounting, and its standard housing geometry supports integration in multi-axis machines.

Peak performance values show the upper operating range for this model. It can draw up to 24.6 A from the inverter and spin at a maximum of 10000 rpm; at that speed, the rotor can produce 17.71 Nm of torque for short bursts such as rapid acceleration. Continuous duty is set by a rated current of 3.6 A, which supports a mechanical output of 1.7 kW. Electrical constants assist drive tuning because the phase windings present 18.8 mH of inductance and 3.9 Ω of resistance, so current control loops can be parameterized for stable bandwidth. Compared with the peak envelope, the stall condition requires only 4.1 A yet locks the shaft with 3.22 Nm, indicating moderate static holding capacity.

The nominal operating point is a shaft speed of 6000 rpm delivering 2.7 Nm at the terminals while supplied with 400 V three-phase AC. Heat is removed through self-cooling by natural convection, so no external blower or liquid circuit is required. A 2-pole resolver mounted on the rear provides rotor position to the controller, allowing smooth vector commutation from zero speed. The enclosure meets IP54, preventing dust ingress and guarding against splashed fluids in factories. Because the cooling airflow passes over the housing, debris build-up is minimized. The resolver feedback remains accurate because the sensor is mechanically separated from the stator iron.
