Product Description:

The P60B18350HBV20 brushless servo motor is built by Sanyo Denki as part of the P6 Super BL Servo Motors series. It employs a permanent-magnet rotor and an integrated absolute sensor to deliver closed-loop axis positioning in automated assembly lines, packaging equipment, and other motion-control systems. By converting drive amplifier output into precise torque and speed, the unit serves as the primary actuator for loads that require repeatable acceleration, velocity regulation, and holding capability during dwell periods.

The motor delivers a mechanical shaft output of 3.5 kW at a nominal speed of 2,000 rpm, producing a continuous torque of 17.0 N·m. During rapid indexing or startup under an unbalanced load, the inverter may command up to 80.2 Arms of phase current, which is higher than the rated current of 26.4 Arms. This temporary current increase supports high acceleration without exceeding the motor’s copper thermal limits. The square frame uses a 180 mm flange pattern, allowing direct coupling to compatible gearboxes or machine plates. This mechanical interface helps keep axial runout low when the motor is face-mounted.

The back-EMF constant is 26.0 mV per min⁻¹ of rotational speed, providing a proportional voltage that the drive can use to estimate motor speed. Current rise is governed by an electrical time constant of 19 ms, while mechanical responsiveness depends on a rotor inertia of 34.1 × 10⁻⁴ kg·m². These dynamic values support proper adjustment of the servo drive’s current, speed, and position control loops. For passive load retention, an integrated holding brake engages when the controller removes excitation. The motor also carries a supercapacitor module that preserves multi-turn position data from the ABS-R II sensor during power interruptions, eliminating the need for a homing cycle after an emergency stop.
