Description: 步进电动机是纯粹的数字控制电动机，它将电脉冲信号转变为角位移，即给一个脉冲，步进电机就转一个角度，因此非常合适单片机控制，在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，电机则转过一个步距角，同时步进电机只有周期性的无累积误差，精度高。-Stepper motor is a pure digital control electric motors, electrical pulse signal will be transformed into angular displacement, that is, to a pulse, a stepper motor on the transfer point of view, SCM is therefore very appropriate, in the non-overloaded case, the motor speed, and stop depending on the location of only pulse frequency and pulse number, and not subject to load changes, motor is a step angle turn at the same time stepping motors only cyclical non-cumulative error and high accuracy.

Description: AC motor drives are widely used to control the speed
of conveyor systems, blower speeds, pump speeds, machine tool
speeds, and other applications that require variable speed with
variable torque. The complete system consists of an ac voltage input
that is put through a diode bridge rectifier to produce a dc output
which across a shunt capacitor, this will, in turn, feed the PWM
inverter.

Description: The need for variable speed of an ac induction motor arises in certain industrial applications and
this is often difficult to achieve because induction motors are of fixed speed. The available control techniques
such as variation of supply voltage, variation of number of poles, are characterized by low efficiency and high
maintenance cost. The improvement in power electronics technology through advancements in semi-conductor
electronic devices with increased reliability and reduced cost led to the development of modern solid-state
variable frequency motor drive which is an electronic device capable of controlling the speed of an induction
motor by varying the frequency with increased efficiency, reliability and low maintenance cost
