Stepper motor is widely used in industry, the performance of the control system planning has an important meaning, when planning requirements inductive thinking stepper motor step Angle, fine fraction, and insist on torque, etc. , make the speed control system with high reliability, the stepper motor to complete the PCC control has great practical value. PCC output of step pulse signal is used to control the position and speed of the stepper motor. That is to say, the stepper motor drive every accept a pulse driving a stepper motor rotation Angle, where a step change the pulse frequency, together make the stepper motor speed change, control the number of pulses, can make the stepper motor positioning accurately, to complete the intention of the stepper motor speed regulation and positioning. PCC output direction of control signal is used to control stepping motor rotation direction, this side is high electricity at ordinary times, motor clockwise, on the other hand, the motor rotate counterclockwise. Resolution (Stepping motor operating steps of a circle)Level set of up to 16, step size from each lap 200 to 508 (each lap）Step 0, can be satisfied the user's different needs. When set, but by the switch on the drive 2 2 to 5. In PCC governor choose each lap count for 1000 steps, where such a stepper motor step Angle of 0. 36 degrees, completely satisfied the demand of the speed regulation system, together because drive adopted niche skills, so for the stepper motor low frequency tremor also played a very good damping effect, enhance the stability and reliability of the system. Stepper motor when stop condition of static determine current there are four kinds of different current levels to choose from. Because the PCC governor of determining torque is small, so pick a static current is 25% of the maximum drive current, to drop step motor temperature rise and extend its life. Shanghai four macros stepper motor engineers claim to make motor can have the maximum moment does not lead to the vibration and noise, in the heart of the PCC governor drive current largest set to 7. 5 a, the power supply voltage of 24 v. Current loop gain press type calculation: Ki = 364, 000 LM/U type of LM -—-Motor inductance (H）U——-The power supply voltage; Note that when the motor demand changes direction, it is necessary to make changes to the direction of control level signal stick to at least 200 us. The PCC control stepping motor used for turbine regulating system, dozens of power station operation results show that the reasonable planning, running in good condition, the stepper motor used in turbine speed, effectively deal with the past governor the low reliability of the question, simplifies the governor layout and decline the cost, can completely satisfied the demand of the turbine speed dynamic and static, has the very high reliability. 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.
