Product Description:
The model 20BM040HXPT4 is a Servo Motor by Sanyo Denki built for precision motion control. It offers robust construction and stable operation for industrial automation tasks. It ensures accurate feedback and control with a square flange, round shaft and integrated optical encoder. It suits applications requiring reliable and efficient motor performance.
The 20BM040HXPT4 servo motor comes housed in a fin cooled aluminum enclosure that promotes effective heat dissipation. This housing supports natural convection cooling that reduces thermal stress without additional fans. A square flange allows easy and secure mounting in compact mechanical assemblies. The motor shaft is round and includes a keyway that provides strong coupling with load mechanisms. Wiring connections are made through a circular industrial grade multi pin connector. The integrated optical rotary encoder in this servo motor delivers incremental feedback with a resolution of 5000 pulses per revolution. The encoder operates at a DC 5 V supply and draws between 200 mA to 250 mA. Signal outputs include channels A, B, Z and their differential complements A-not, B-not and Z-not. The differential signal design enhances noise immunity that supports reliable operation in electrically noisy environments.
The 20BM040HXPT4 servo motor encoder’s includes a chassis ground and supplies an index pulse per revolution for positional referencing. Mounting of the encoder is done directly at the motor's rear using a dedicated end cap enclosure. The sensor is optical and directly attached to the motor shaft that offers precise feedback with minimal backlash. The motor's encoder feedback system uses quadrature signals with index. This enables fine positioning and direction sensing. The pin configuration of the encoder clearly separates power, signal and grounding which aids in reliable integration with controllers.
