Product Description:

The P50B08075DCS80 is a brushless AC servo motor built by Sanyo Denki for the P5 Super BL Servo Motors series. As a rotary actuator, it accepts commanded current from a matched amplifier and delivers proportional torque to machine elements that require accurate positioning or velocity regulation. Typical roles include driving pick-and-place heads, indexing tables, or feed rollers where responsive clockwise and counterclockwise motion must repeat within tight tolerances across a production shift.

At its rated operating point, the motor outputs 750 W of mechanical power while maintaining a shaft speed of 3,000 rpm; this pairing establishes the continuous operating range used during closed-loop control. The corresponding rated torque of 2.381 N·m is available continuously under ambient cooling. When the shaft is locked, the motor provides a continuous stall torque of 2.94 N·m, which helps the drive resist load movement on vertical axes. Achieving those levels requires a phase current of 6.0 A. With a torque constant of 0.447 N·m/A RMS, the drive can estimate torque production from real-time current feedback.

Short-duration demands such as acceleration are served by an instantaneous maximum torque of 8.82 N·m, providing nearly three times the continuous rating for rapid startups. Copper losses generated during these events are moderated by a phase armature resistance of 0.43 Ω, which helps the controller set voltage margins and thermal limits. Dynamic response is further influenced by a rotor inertia of 1.926 × 10^-4 kg·m². This low moment of inertia allows quick reversals while still damping microvibrations that could affect optical or metering stations. The housing carries an IP55 protection rating, providing resistance to dust ingress and low-pressure water jets so the motor can be mounted on open machine frames without additional covers.
