Product Description:

The P50B04010DXS07 is a brushless servo motor produced by Sanyo Denki in the P5 Super BL Servo Motors series. Designed for compact industrial axes, it converts drive current into precise rotary motion for pick-and-place heads, small conveyors, and electronic assembly equipment. Its wiring-saving incremental encoder supplies position feedback without requiring separate sensor cabling, making the unit suitable for densely packed control cabinets.

The motor delivers a rated mechanical output of 100 W at a shaft speed of 3000 rpm, producing a continuous rated torque of 0.319 N·m. This operating point requires a phase current of 1.0 Arms, and the standardized 40 or 42 mm square flange mounts directly to miniature gearboxes and machine frames. The continuous stall torque is 0.353 N·m, and the continuous stall current is 1.2 Arms. A rated power rate of 13.8 kW/s supports fast load acceleration in compact motion systems. Electrical characteristics include a phase resistance of 7.0 Ω and an electrical time constant of 1.5 ms. The induced voltage constant is 11.6 mV per rpm with a tolerance of ±10%, which helps determine regenerated voltage during deceleration. The motor has no holding brake, so external clamping or drive torque must maintain the shaft position when power is removed.

For short bursts, the shaft can withstand an instantaneous stall torque of 0.98 N·m when the amplifier supplies up to 3.6 Arms. The rotor’s low inertia combines with a mechanical time constant of 1.4 ms to support rapid starts and stops. A torque constant of 0.333 N·m/Arms provides a linear relationship between commanded current and developed torque. Operation continues at speeds up to 4500 rpm, providing headroom for brief overspeed movements or field-weakening control. During deceleration, braking energy is managed electronically by the drive. The brushless design reduces mechanical wear, while the incremental encoder provides the feedback required for repeatable positioning throughout the operating speed range.
