Sanyo Denki P20BM040HXDT0 AC Servo Motor

Module Feature

Sanyo Denki P20BM040HXDT0 belongs to SANMOTION series AC brushless servo motor. Rated power 400W, AC200V class, low inertia rotor design. Built-in high resolution rotary encoder for closed-loop position feedback. Compact flange structure, high torque density and excellent low-speed running performance. Reinforced bearing assembly, strong vibration resistance. No built-in power-off holding brake, suitable for horizontal axis positioning. Widely used for medium-small load positioning axis in semiconductor wet bench and chemical delivery automation equipment.

Working principle: The matched servo amplifier outputs three-phase AC power to motor windings. The built-in encoder continuously feeds rotor angle and speed signal back to servo drive. The drive performs real-time closed-loop calculation and adjusts output current to achieve precise torque, speed and position control. Without power-off brake, external mechanical locking should be used for vertical load.

System compatibility

Matched with Sanyo Denki R12A831802 servo drive, used for automation equipment horizontal axis motion positioning.

Function

P20BM040HXDT0 servo motor manufactured by Sanyo Denki. It provides high precision rotary motion and position control for medium-small load. Winding damage,encoder failure or loose coupling will trigger servo alarm and stop movement. It is motion actuator for semiconductor wet bench and chemical delivery automation equipment.

Installation

Follow lockout/tagout safety procedure before installation. Power off servo drive system. Align motor shaft with load coupling, fasten flange bolts securely. Wire motor power cable and encoder feedback cable. Configure servo parameters via SANMOTION software, perform jog test and positioning test before formal operation.

Interface3-phase power connector, encoder feedback connector on housing of P20BM040HXDT0.

Diagnostic

Motor cannot rotate:Power wiring error, servo enable signal missing. Positioning inaccuracy:Encoder fault, loose coupling or servo gain mismatch. Overheat alarm:Overloaded load or bearing wear. Abnormal running noise:Bearing damage or shaft misalignment.
