Product Description:

The P50C07020DXS21 is a brushless AC servo motor built by Sanyo Denki for the P5 Super BL Servo Motors series. It converts commands from a servo amplifier into tightly regulated shaft rotation, supporting accurate point-to-point movement in compact handling equipment, small gantries, and electronic assembly stages. By integrating an incremental encoder and a rare-earth magnet rotor, the unit enables closed-loop speed and position control on axes that require fast response within the limited space of industrial automation cells.

Continuous mechanical output reaches 200 W, with a rated shaft torque of 0.637 N·m at a nominal rotor speed of 3,000 rpm. For rapid indexing, the drive can increase the speed to 4,500 rpm, helping reduce cycle times in pick-and-place or probe applications. Short load spikes are supported by an instantaneous peak torque of 1.96 N·m, so transient disturbances are less likely to stall the axis. These powertrain ratings allow the motor to operate light conveyors, lead-screw tables, or gear-reduced joints. The available peak torque also supports brief acceleration and deceleration demands during repetitive positioning cycles without changing the motor’s continuous output rating.

The electrical interface is rated for 200 VAC, allowing compatible mid-power servo amplifiers to power the stator without a step-down transformer. Position feedback comes from a wire-saving incremental detector that generates 2,000 pulses per revolution and reduces the number of conductors needed for feedback wiring. A square 76 mm flange follows IEC mounting conventions and supports direct alignment with a coupling or ball-screw assembly. The enclosure is rated at IP55 except at the shaft end, providing resistance to dust and water jets in general machine environments. The motor is supplied without a holding brake, so vertical axes must use external clamping or drive-applied torque to retain a static load. This brake arrangement should be considered when the connected mechanism must remain stationary after motor power is removed.
