Product Description:

The P80B22250HXS2H is a brushless servo motor built by Sanyo Denki for the P8 Super BL Servo Motors series. As a compact drive element, it converts electrical power into tightly regulated motion for positioning tables, pick-and-place axes, and similar automation tasks. The motor uses a wire-saving incremental encoder to provide real-time shaft feedback to the drive without additional I/O conductors. Its 220 mm mounting flange allows direct attachment to heavy machinery frames.

During continuous operation, the unit delivers 2.5 kW of mechanical power at a rated shaft speed of 2,000 rpm, generating a continuous torque of 12.0 N·m. To sustain this output, the windings draw a phase current of 21.4 A rms, while an enclosure rating of IP67 protects the stator against dust ingress and temporary submersion. The encoder supplies 2,000 pulses per revolution, providing a position increment of 0.18 degrees per pulse. A torque constant of 0.66 N·m per ampere relates the commanded current to the torque produced by the motor. The rotor inertia is 27.1 × 10⁻⁴ kg·m², which moderates speed changes and helps the load start or stop without overshoot. Because the motor has no holding brake, mechanical clamping or drive torque must secure vertical axes when power is removed.

For short operating intervals, the motor withstands a peak stall torque of 30.0 N·m, allowing machines to overcome static friction before settling into continuous duty. Copper losses are limited by a phase resistance of 0.056 Ω. The electromagnetic field reaches its rated magnitude within an electrical time constant of 27 ms, supporting fast current loops in digital drives. The frame weighs 15.5 kg, providing sufficient mass for vibration damping while remaining suitable for slide-mounted assemblies. A maximum speed of 3,000 rpm expands the usable operating range. The brushless design eliminates commutator wear and reduces routine maintenance requirements.
