Product Description:
The P80B22450RCSAA is a brushless servo motor produced by Sanyo Denki within the P8 Super BL Servo Motors series. It converts drive-amplifier current into precise mechanical rotation for medium-to-large industrial axes that require responsive positioning and repeatable velocity. The integration of a permanent-magnet rotor with an encoder allows the unit to operate as the primary actuator in machining centers, material-handling lines, and automated assembly systems.
During continuous operation, the motor supplies a rated output of 4.5 kW at a rated speed of 2,000 rpm, generating a rated torque of 21.5 N·m while drawing 24.1 A RMS from the inverter. The wiring-saving incremental encoder returns position data with a resolution of 2,000 P/R, enabling tight control-loop bandwidths without additional I/O lines. Its encoder design reduces cabinet wiring by carrying the required connections in a consolidated harness. Continuous stall torque reaches 32.0 N·m, while the rotor inertia of 58.1 × 10⁻⁴ kg·m² supports stable acceleration profiles. The brushless magnetic circuit has a torque constant of 1.05 N·m/A RMS, helping the motor maintain smooth torque production across its operating range. These characteristics support accurate velocity and position control during sustained industrial duty.
For transient operation, the electromagnetic structure can reach a peak stall torque of 70.0 N·m, while the permissible mechanical speed extends to 2,500 rpm for fast indexing moves. A built-in holding brake operates at 24 V and 1.6 A, clamps with 32.0 N·m of torque, and adds 9.9 × 10⁻⁴ kg·m² of inertia. Mounting uses a 220 mm square flange that aligns the stator with large machine frames. A phase resistance of 0.043 Ω minimizes copper losses during repeated acceleration, and the brushless drive design preserves efficiency during demanding duty cycles. The brake secures the connected load when the motor is stopped, while the large flange provides a rigid interface for applications such as gantry robots and high-speed palletizers.
