Product Description:

The P50B03003DXL9X is a miniature servo motor manufactured by Sanyo Denki for the P5 Super BL Servo Motors series. As a brushless design, it delivers low-maintenance rotary motion for indexing tables, semiconductor tooling, and other precision axes in industrial automation. Its compact mechanical profile supports installation with small gearheads, while its 67.5 mm overall length helps minimize enclosure depth. A fully enclosed, self-cooling housing and Class F winding insulation allow reliable operation in tightly packed control cabinets where forced ventilation is limited.

Under continuous duty, the unit produces 30 W of mechanical power at a rated speed of 3000 rpm. This operating point corresponds to a rated torque of 0.098 N·m at a phase current of 0.5 Arms, allowing a low-power inverter to drive the motor. The copper windings have a phase resistance of 20.5 Ω, which limits current during startup and supports stable current-loop tuning. A square mounting face of 35 mm centers the motor without extra adapters, and the 5 mm shaft diameter transmits torque directly to timing pulleys or couplings. The sealed housing does not require airflow through the motor, helping prevent its cooling needs from affecting nearby electronics. Its small dimensions and low output rating make it suitable for precision mechanisms that require controlled movement within limited installation space.

The motor has a 0.7 ms electrical time constant and a 2.1 ms mechanical time constant, allowing rapid current rise and speed changes. When commanded by the controller, the rotor can reach a maximum speed of 4500 rpm or briefly deliver a stall torque of 0.323 N·m during demanding positioning events. The winding torque constant of 0.206 N·m/Arms links current commands to produced torque, enabling accurate feed-forward compensation in servo control loops. The motor does not include an internal holding brake, so an external clamping device is required when the shaft must remain stationary after power is removed.
