Product Description:
The P60B18550RXS0EM servo motor is produced by Sanyo Denki for the P6 Super BL Servo Motors series. This brushless AC unit is intended for industrial automation tasks that require high power density and precise velocity regulation. A wiring-saving incremental encoder with 2,000 pulses per revolution attaches directly to the rear housing, providing position feedback without additional cabling. This arrangement supports closed-loop control of indexing tables, gantry axes, and packaging equipment where repeatable motion is critical.
The motor draws a continuous armature current of 32 A RMS, establishing the drive capacity needed for steady operation. Under that load, it produces a nominal torque of 35.0 N·m, representing the sustained twisting force available at the shaft. Mechanical output reaches 5.5 kW when the rotor operates at its nominal speed of 1,500 rpm. A torque constant of 1.18 N·m/A RMS links commanded current to instantaneous torque, supporting precise current-mode control. The square mounting flange measures 180 mm, allowing direct installation on compatible machine frames. The motor also has a phase resistance of 0.040 Ω and uses brushless construction to reduce maintenance. It does not include an embedded holding brake, so the machine or drive must retain static loads when the shaft is stopped.
High-demand moves are supported by a peak torque capability of 88.3 N·m, providing nearly 2.5 times the nominal torque for acceleration or disturbance rejection. Dynamic response is supported by a rotor inertia of 61.9 × 10⁻⁴ kg·m² and a mechanical time constant of 0.52 ms, allowing rapid speed changes with minimal settling time. The shaft can reach a maximum speed of 2,500 rpm before voltage limits are reached. The motor has a voltage constant of 41.2 mV per min⁻¹ and an electrical time constant of 23 ms. Its stall torque is 37.3 N·m, while its mass of 31.7 kg contributes to mechanical stability and heat dissipation. CE and UL certifications indicate compliance with applicable safety and electromagnetic compatibility requirements for industrial installations.
