Product Description:

The P50B08050DXS00 is a brushless AC servo motor manufactured by Sanyo Denki for the P5 Super BL Servo Motors series. In industrial automation equipment, it functions as a closed-loop actuator that supplies precise rotary motion to positioning tables, pick-and-place heads, and other axes that require rapid acceleration and repeatable speed control. This standard-design motor integrates a wiring-saving incremental encoder so the drive can read the rotor position directly while reducing the amount of external cabling inside the control cabinet.

During continuous operation, the unit delivers a mechanical output of 500 W while producing a rated shaft torque of 1.589 N·m at a rated speed of 3,000 rpm. These operating values correspond to a rated phase current of 3.9 Arms and a phase resistance of 0.94 Ω, which the drive uses to calculate voltage commands. The IP55 enclosure protects the windings from dust and low-pressure water jets, allowing the motor to operate outside a sealed control cabinet. The encoder provides 2,000 pulses per revolution and operates with a 5.2 ms electrical time constant and a 1.5 ms mechanical time constant, allowing the control loop to track speed changes with minimal lag. A flange measuring 80 or 86 mm and a 16 mm shaft allow the frame to connect with common gearheads.

For peak movements, the motor can generate up to 5.88 N·m, and the servo system may command momentary speeds as high as 4,500 rpm without demagnetizing the motor. This short-term performance is supported by a torque constant of 0.473 N·m/Arms, allowing the amplifier to estimate instantaneous torque from the supplied current. The housing is 126 mm long, and the total mass of 3.0 kg supports installation on lightweight positioning stages. The motor has no holding brake, so vertical axes must use an external mechanism to maintain their position when power is removed. Its brushless construction eliminates brush wear and reduces the maintenance associated with conventional brushed motors.
