In 1, the stepper motor is a special motor as control, it is the rotation of the fixed point of view ( known as" angle" ) running step by step, which is characterized by no accumulated error ( accuracy of 100% ), so it is widely applied in a variety of open loop control. Stepper motor running an electronic device to be driven, this device is the stepper motor drive, it is the control system of the pulse into the stepper motor angular displacement, or: control system each send a pulse signal, the driver makes the rotation of the stepper motor step angle. So the stepper motor speed and the frequency of the pulse signal proportional to. So, control the stepping pulse signal frequency, for precise speed control of stepping motor; the number of pulse, the precise positioning of purpose motor;2, step motor subdivision drive through the drive, the step angle is small, such as a driver in the 10 subdivision, the step angle only as ' natural ' motor step angle 1/10, that is to say: ' when the driver in the no subdivision of the whole step state, each made of a control system stepping motor pulse, rotate 1.8 degrees; and subdivision driver in the 10 subdivision, motor rotary 0.18 degree ', this is subdivision of the basic concept. Subdivision is composed entirely of drive by precise control of motor phase current is generated, and the motor.
Sunrise Motor was founded in 2003 and specialised on development, production and sales of electric motor products to answer to the growing demand for these commodities on the intl’ markets.
