What is an AC stepper motor?

Stepper motor is a kind of electrical impulse signals into angular displacement or linear displacement of the open-loop stepper motor control element pieces. In the absence of overload, the motor speed and stopping position depends only on the frequency and number of pulses sent a pulse signal, and not because of load variation affected, whenever the stepper motor driver receives a pulse signal it will drive a stepper motor to rotate in one direction previously set a fixed angle. We can send it by controlling the number of pulses to control the amount of angular displacement, so as to achieve precise positioning;Meanwhile, we can also control the pulse frequency to control the rotational speed and acceleration of the stepper motor, so as to achieve the purpose of our governor.
Because of this linear relationship exists, and the stepping motor only periodic error without accumulated error and so on. So in the field of speed control, position, etc. to control the stepping motor becomes very simple. While stepping motor has been widely used, but not like a normal stepper motor and DC motors, AC motors under General. It must be by a two-ring pulse signal, power driver circuit composed of the control system can be used.
Stepping Motor Works
 
  When current flows through the stator windings, stator windings produces a magnetic field vector. This magnetic field will lead to an angle of rotation of the rotor so that the stator magnetic field direction is consistent with a pair of magnetic field direction of the rotor. When the stator of the rotating magnetic field vector angle. Along with the magnetic field of the rotor rotation angle. Each input an electrical pulse, the motor rotation angle forward. The number of pulses is proportional to the angular displacement of the input of its output, speed and pulse frequency proportional. Change the order of winding is energized, the motor will reverse. Therefore, the number of pulses can be used to control power-up sequence, the frequency and the motor windings of each phase to control rotation of the stepping motor.
  Usually see all kinds of motors, we are all internal core and windings of the coil. Winding resistance, power will generate losses, losses proportional to the square of the size of the resistance and current, this is what we often say that the copper loss, if the current is not a standard DC or sine wave, but also have harmonic loss; core has hysteresis eddy current effects in the alternating magnetic field will produce losses, the size and material, current, frequency, voltage, called iron loss.
Copper and iron losses are manifested in the form of heat, thus affecting the efficiency of the motor. Stepper motors are generally pursue positioning accuracy and torque output, efficiency is relatively low, current is generally relatively large and harmonic components, the frequency of the alternating current with the speed of change, thus stepping motor heat prevailing circumstances and conditions than the general severe AC motor.
Tsu'tey motor (SAMSR MOTOR) has over 30 years of motor, stepper motor and drive manufacturing history, along with the development of automated Assunta motor (SAMSR MOTOR) are becoming increasingly toward high-precision, superior technology and comprehensive.
Tsu'tey motor (SAMSR MOTOR) hybrid stepper motors using rare earth permanent magnet materials, compared with other brands stepper motor with a small magnetic loss, high efficiency, good dynamic performance advantages. Also Tsu'tey motor (SAMSR MOTOR) has a control program is highly integrated, flexible design, control and stability, precise positioning and so on. It sophisticated technology leader in the motor industry, is the first choice for many years all industrial equipment to improve product quality.
Changzhou Tsu'tey stepper motors and stepper motor drives are widely used in automatic control, precision machining, aerospace technology, consumer products, medical devices, robotics, underwater facilities, textile, semiconductor equipment, packaging machinery, transportation machinery and factory automation that require precise positioning, the field of high-precision, automatic aiming and automatically records and the like.
