Product Description:
The P60B18450RXV20 is a brushless AC servo motor manufactured by Sanyo Denki for the P6 Super BL Servo Motors series. Intended for precision axis control in industrial automation, it combines a 180 mm mounting flange with an absolute sensor (ABS-R II) that retains position data across power cycles. A built-in supercapacitor supports the sensor’s memory function, eliminating the need for an external battery. Because the unit is supplied without a holding brake, applications that require mechanical shaft locking must use an external brake or locking mechanism.
The motor delivers a rated mechanical output of 4.5 kW, generating a continuous torque of 21.5 N·m at a nominal speed of 1,500 rpm. Under stall conditions, it can draw 34.0 A RMS while sustaining a shaft torque of 32.0 N·m, which assists with thermal sizing for the drive and cabling. Electrical losses are limited by a phase resistance of 0.052 Ω, and the rated current of 24.9 A RMS supports stable operation within the motor’s thermal limits. A rated power rate of 98 kW/s indicates how quickly the motor can reach its working point, while an electrical time constant of 23 ms indicates the delay between applied voltage and current rise. The induced-voltage constant of 36.0 mV/rpm helps the controller account for back electromotive force during high-speed operation.
The motor can reach 2,500 rpm during short-term velocity peaks and produce a maximum stall torque of 70.0 N·m. These operating peaks require up to 81.2 A RMS from the inverter, so the current loop must accommodate the increased demand. A mechanical time constant of 0.69 ms supports rapid speed response when operating conditions change. The torque constant of 1.03 N·m/A RMS indicates the relationship between motor current and generated torque. Its brushless design reduces wear associated with mechanical commutation and supports smooth motion in gear-driven or direct-drive machinery.
