Advantages of stepping motor

2014/07/08

 Stepping motor is a kind of electric pulse signal into angular displacement to control the micro motor rotor rotation. Driving power of stepping motor by frequency pulse signal source, a pulse distributor and a pulse amplifier, thereby driving power provides the pulse current to the motor windings. The running performance of stepping motor depends on the motor and the driving power of good cooperation. Stepping motor has the advantages of no accumulative error, simple structure, convenient repair and use, low manufacturing cost, stepper motor drive load inertia, applicable to small and medium-sized machine tools and precision requirement is not high, disadvantage is low efficiency, large heat, sometimes "out of step".

The advantages of stepping motor:

1, overload is good: its speed is not influenced by loads, unlike ordinary motor, when the load will appear decline rate increases, the stepper motor used for speed and position has strict requirements.

2, convenient control: stepper motor is to "step" as the unit of rotary, digital obvious features.

3, the structure is simple: mechanical speed and position control of traditional structure is more complex, difficult to adjust, the use of stepper motor, which makes the structure simple and compact, the speed of motor speed is converted to a voltage, and transfer to the input end as the feedback signal. Motor speed as an auxiliary motor, speed motor is arranged on the tail end of ordinary DC motor, speed motor voltage through the feedback to the DC power supply, to achieve the purpose of speed control of a DC motor.
