Product Description:

The P10B10075HBS20 is a brushless servo motor from Sanyo Denki, supplied in the P1 Super BL Servo Motors series. Designed for closed-loop positioning and velocity control, the unit converts electrical power into precise mechanical torque for automated machine axes, pick-and-place heads, or packaging actuators. A reduced-wiring incremental encoder fitted to the rear of the frame sends position feedback directly to the drive, allowing synchronous operation with minimal cabling.

The motor has a rated mechanical output of 750 W and produces a shaft torque of 3.5 N·m at its nominal speed of 2,000 rpm. When additional speed is required during acceleration, the rotor can reach 3,000 rpm. The square flange measures 100 mm on each side, simplifying attachment to standard gearheads and mounting plates. At the rated operating point, the stator windings draw 5.1 Arms and have a phase resistance of 1.05 Ω, while the electromagnetic coupling provides a torque constant of 0.81 N·m/Arms. The back electromotive force follows a constant of 28.5 mV per rpm, supporting stable drive regulation across the operating range.

Dynamic behavior is influenced by an electrical time constant of 3.0 ms and a mechanical time constant of 6.5 ms, giving the servo a quick current rise and rotor response during rapid indexing. Peak stall torque reaches 10.8 N·m, allowing the axis to overcome short-term inertial or frictional loads without losing synchronization. The incremental encoder provides 6,000 pulses per revolution of positional resolution, allowing the controller to command angular movements as small as 0.06 degrees. A spring-applied, power-off brake rated at 3.9 N·m holds the shaft when the system is disabled, and its coil releases at 90 V to resume motion. Rotor inertia is 14.08 × 10⁻⁴ kg·m², balancing torque stability with fast directional reversals.
