After the 90 s, countries around the world have been commercialized step of communication system is controlled using digital sine wave stepper motor driver. Ac stepping drive unit in the field of drive development with each passing day.
at present, the new type of permanent magnet ac stepper motor has developed rapidly, especially from the square wave to control the development to the sine wave control, better system performance, its wide range of speed regulation, and especially superior performance at low speed.
the traditional communication stepper motor features soft, and its output characteristic is not a single value. Stepper motor generally unable to pinpoint for open loop control, speed of the motor itself and the resonance zone, PWM speed control system of position tracking performance is poorer, frequency control of motor speed is relatively simple but sometimes not enough accuracy, dc stepper motor system for its excellent performance has been widely used in the position servo system, but its disadvantages, such as complicated structure, the contradiction in dead zone in super-low speed and commutator brush will bring noise and maintenance problems.
the stepping system: is the location of the object, location, status, etc is accused of output can follow the input target (Or a given value)Any change of the automatic control system. Step by step, according to the requirement of the control command is the main task of the power amplification, transformation and regulation, such as processing, driving device, the output torque, speed and position control is very convenient.
as a result, in a step by step system must adopt high precision measuring element, such as precision potentiometer, selsyn, rotating transformer, photoelectric encoder, grating, magnetic grid and grid, and so on. In addition, also can take additional measures to improve the precision of the system, such as measuring element (Such as selsyn)Measurements are connected to the rotor shaft through the gear reducer, the rotation Angle is amplified, to improve the relative accuracy of measurement.
step progress motor adopts the scheme of the stepping system called fine coarse measurement and control system or dual channel system. By meshing gear reducer and the rotation Angle measuring circuit said the reading passage, taken directly from the rotation Angle measuring circuit called coarse reading passage.
the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire. Telephone:
