Product Description:
The P50B07020PXS00 is a brushless servo motor produced by Sanyo Denki within the P5 Super BL Servo Motors series. As a standard motor, it uses brushless technology to deliver closed-loop rotary motion for positioning tables, pick-and-place heads, and other automation axes. A 76 mm square flange facilitates mounting to compact gearboxes, while the overall length of 97 mm keeps the required installation depth short.
Under continuous rated operation, it provides 200 W of mechanical power at a shaft speed of 3,000 rpm. The resulting shaft torque is 0.637 N·m with a phase armature current of 4.3 A rms. A phase resistance of 0.66 Ω establishes the voltage required to reach this current and contributes to copper losses that must be removed through the housing. The rotor inertia is 0.386 × 10⁻⁴ kg·m², allowing drive controllers to achieve rapid changes in velocity without large control gains. Dynamic response is further characterized by a mechanical time constant of 2.3 ms and an electrical time constant of 3.6 ms. These time constants indicate how quickly the motor responds and develops torque after the windings are energized.
For applications that require short bursts of higher output, the rotor can accelerate to a top speed of 4,500 rpm. The motor provides a continuous stall torque of 1.96 N·m, allowing the axis to hold a stationary load when commanded. When the motor temperature remains within its operating limits, the drive may supply up to 14.4 A rms during stall conditions. The torque constant is 0.18 N·m/A rms, indicating the relationship between armature current and shaft torque. Position feedback is supplied by a wire-saving incremental encoder that produces 2,000 pulses per revolution and reduces the number of required sensor conductors. The 14 mm shaft diameter accommodates keyed couplings, while the absence of a holding brake means that an external restraint must secure vertical loads when power is removed.
