Hybrid Stepper Motors 2 Phase Stepper Motor For Mechanical Equipment Feature:1. The stepper motor adopts high-quality bearing, with low self-inductance, good response and low operating temperature.2. An advanced inner rotor is used, and the surface is coated with imported impeller glue to prevent burrs caused by oxidation causing engine noise.3. The stepper motor has low resistance, good thermal conductivity, and can operate at a safe temperature.4. 2 phase hybrid 42 stepper motor, larger production torsion with step angle of 1.8 degrees.5. With a shaft of 5mm diameter, it runs more smoothly and is often used in various mechanical transmission equipment.
