Product Description:
The P80B22250HXS20 is a brushless servo motor developed by Sanyo Denki within the P8 Super BL Servo Motors series. Using permanent-magnet synchronous technology, it provides precise rotary positioning and speed regulation for conveyor axes, indexing tables, and pick-and-place heads in automated production lines. An integrated incremental encoder with simplified wiring supplies feedback channels without requiring separate encoder connectors, enabling straightforward integration with compatible digital drives. The 220 mm mounting flange allows the motor to fit large-frame gearboxes and transfer mechanical power to demanding motion-control applications.
During continuous duty, the motor delivers a rated mechanical output of 2.5 kW at a shaft speed of 2000 rpm, producing a sustained torque of 12.0 N·m. To maintain this operating point, the windings draw 21.4 A RMS from the inverter. When the load requires higher short-term torque, the electromagnetic circuit withstands a stall torque of 30.0 N·m. The current may temporarily rise to 55.0 A RMS under this condition. The drive must manage these thermal and electrical loads through current limiting and appropriate duty-cycle control to prevent excessive winding temperatures during repeated acceleration or stall events.
A torque constant of 0.66 N·m/A RMS indicates how much shaft torque is produced for each ampere commanded, allowing the controller to regulate force output accurately. An electrical time constant of 27 ms, combined with a mechanical time constant of 1.1 ms, shows that current rise is slower than rotor acceleration. This difference allows current-loop and motion-control responses to be adjusted according to the connected load and drivetrain inertia. The steel-cored motor weighs 15.5 kg, which helps moderate vibration and provides thermal mass, while its 52 kW/s power rate supports rapid energy conversion during acceleration. The motor is supplied without a holding brake, so an external locking device is required when a vertical axis must remain stationary after motor power is removed.
