Product Description:

The P80B22450LCX2C servo motor is produced by Sanyo Denki within the P8 Super BL Servo Motors series. This brushless AC unit converts electrical energy into controlled shaft rotation for positioning and speed regulation tasks in industrial automation lines. Sanyo Denki combines P8 motor technology with an internal permanent-magnet rotor and an integrated holding brake that keeps loads stationary when power is removed.

The motor has a rated output of 4.5 kW at a rated speed of 2,000 rpm, where the shaft develops a rated torque of 21.5 N·m. Supplying this load requires a phase current of 24.1 A rms, while short-duration demands can be met by a peak stall torque of 70.0 N·m. The motor is rated for continuous operation, and its electric time constant of 33 ms indicates the current rise response of the stator windings. A phase resistance of 0.043 Ω helps minimize copper loss, while a rotor inertia of 58.1 × 10⁻⁴ kg·m² balances acceleration with rotational stability. Torque is produced by the brushless design, so electronic commutation provides maintenance-free operation without mechanical brushes. The holding brake operates from a 24 V supply and secures the connected load when motor power is unavailable.

The motor attaches to machinery through a 220 mm square flange, and its 35 mm keyed shaft end transmits torque through compatible couplings. The enclosure has an IP67 rating, providing complete protection against dust and allowing temporary immersion when the cable glands are fitted correctly. The insulation system withstands 1,500 VAC for one minute. Insulation resistance remains at least 10 MΩ when tested with 500 VDC, supporting safe operation with inverter outputs. The motor has a torque constant of 1.05 N·m/A rms, allowing the drive to regulate output torque accurately in response to commanded current.
