What is the difference between ordinary motor, step motor and servo?
Servo motor, construction is similar to synchronous motor! But the drive circuit is the feedback automatic correction digital servo control! High precision! High precision instrument and automatic control machine! Digital pulse drive!
Step motor, rotor is permanent magnet type corresponding magnetic pole! Controlled in stator pulsed magnetic field can achieve precision step in! Apply to instrument and automatic control and drag! Less accurate than servo motor!
The ordinary motor, the motor is uncontrollable torque! Both start and stop have delays and inertia! Adapt only to conventional power drag!
