Sanyo Denki 103H5505-70E1 MUF1-87 Stepping Motor System

Module Feature

Sanyo Denki 103H5505-70E1 MUF1-87 is a complete five-phase hybrid stepping motion system, including 103H5505-70E1 stepping motor and matched MUF1-87 five-phase stepping driver. The motor adopts hybrid magnetic circuit structure, small 0.72° full step angle, high positioning repeatability, low vibration and low running noise. The MUF1-87 driver supports microstep subdivision function, multi-stage current setting and pulse command input. Built-in multi-protection functions including overcurrent and overheat protection. Widely used for precision positioning axes in semiconductor automation, inspection equipment and small automation machinery.

Working principle

The MUF1-87 stepping driver receives pulse and direction command signals from upper controller, and outputs sequential multi-phase current to motor windings. Alternating magnetic field drives the hybrid rotor to rotate at fixed step angle according to pulse quantity, realizing open-loop position control. The driver supports microstep operation to reduce vibration. When overcurrent or overtemperature fault is detected, the driver will cut off output to protect motor winding.

Onboard components

Motor: Hybrid rotor, multi-phase stator winding, front and rear bearing set, motor housing, shaft oil seal, multi-phase power terminal connector. Driver MUF1-87: Main control board, power switching circuit, pulse signal processing circuit, status LED indicators, fault detection circuit, power and motor terminal block.

LED indicators
