Product Description:
The P20B10100DXS0J is a brushless AC servo motor produced by Sanyo Denki for the P2 Super BL Servo Motors series. Designed to drive moderate-power axes in assembly cells, it pairs a wiring-saving incremental encoder with a resolution of 2,000 pulses per revolution to report the shaft angle directly to the drive while reducing sensor wiring. Its compact design and digital feedback support precise velocity and position control in pick-and-place units, indexing tables, and other industrial automation equipment that requires continuous-duty accuracy.
A 100 mm square flange fits standard mounting patterns, while the overall length of 147 mm reduces the installation depth required inside machinery. A 22 mm shaft transmits torque through keyed hubs and couplings. At its continuous operating point, the unit delivers 1,000 W while rotating at 3,000 rpm. This output corresponds to a continuous torque of 3.19 N·m produced with a phase current of 6.9 Arms. The winding resistance is 0.51 Ω, and the torque constant is 0.53 N·m/Arms, allowing the drive to estimate the applied load from measured current. A voltage constant of 18.6 mV/rpm supports back-electromotive-force monitoring during dynamic regulation. The brushless design avoids the wear and maintenance associated with mechanical commutators.
Dynamic response is supported by an electrical time constant of 11 ms and a rotor inertia of 1.55 × 10⁻⁴ kg·m², allowing commanded torque changes to reach the shaft quickly. The motor can reach a maximum speed of 4,500 rpm during short operating intervals. Its instantaneous stall torque peaks at 10.3 N·m, providing additional torque for acceleration and sudden load changes. The housing weighs 5.4 kg, keeping the motor manageable for moving-axis gantries while providing sufficient rigidity to reduce vibration. Because the motor is supplied without a holding brake, an external clamp or another mechanical holding device must retain the load when power is removed. The phase windings and wiring-saving encoder connection reduce the number of separate conductors required during installation.
