28mm Round Flange Small Precision Planetary Gearbox With Hybrid
Motor
Stepper motor
Step motor, also known as pulse motor, is based on the most basic
electromagnet principle. It is a kind of electromagnet that can
rotate freely. Its action principle is to generate electromagnetic
torque based on the change of air gap permeability.
Stepper motor is an open-loop control motor that converts
electrical pulse signals into angular or linear displacement.
Stepper motor is a kind of induction motor, its working principle
is the use of electronic circuit, the direct current into
time-sharing power supply, polyphase timing control current, using
this current to power stepper motor.
Normally, the driver is the time-sharing power supply for stepper
motor, polyphase timing controller.
As an executive component, stepping motor is one of the key
products of mechatronics. With the development of microelectronics
and computer technology, the demand for stepping motor is
increasing day by day, and it is applied in various fields of
national economy.
