Stepper motor is also called the pulse motor, including reactive stepper motors, permanent magnet stepping motor, hybrid stepping motor, etc. (1)Reactive stepping motor, also called induction, hysteresis or reluctance stepper motor. The stator and rotor are made of soft magnetic materials, uniform distribution on the stator of large pole with multi-phase exciting winding, fixed, rotor around uniformly distributed small teeth and slots, after electrify torque caused by the change of permeability. Generally for three, four, five, six phase; Can achieve high torque output; Step away from the Angle of small; When power is no positioning torque; The motor damping is small, single step operation shock for a long time; Starting and running frequency is higher. (2)Permanent magnet stepper motor, motor rotor made of permanent magnetic materials, usually made of soft magnetic materials multiphase field winding of the stator, fixed, no small teeth and surrounding the rotor slot, after electrify use of permanent magnets and the stator current magnetic field interact to produce torque. General for two phase or four phase; Small output torque; Step away from the Angle of; Have a certain holding torque when power; Starting and running frequency is low. (3)Hybrid stepping motor: also called permanent magnet reactive, permanent magnetic induction stepping motor, a mixture of permanent magnet and the advantages of reactive. Its four phase reactive stepper motor stator and there is no difference, the rotor structure is more complicated. General for two phase or four phase; Must supply the positive and negative pulse signal; The output torque is permanent magnet; Step away from the Angle of relatively permanent magnet is small; When power is no positioning torque; Starting and running frequency is higher; Is a kind of stepping motor is now developing rapidly. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
