Electrical network board type furniture commonly used cutting machine so the drive motor is divided into two kinds, step motor and servo motor. Equipment running speed related to control system, it also related to the drive motor. Stepper motor is the electrical pulse signal into angular displacement or linear displacement of open loop control elements. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by the load change. Servo motor servo system refers to the manipulation of the mechanical components work in the engine, is a direct subsidy motor variable speed device. Then open the machine equipment is stepping motor and servo motor good? 1. First of all, from the control precision, precision stepper motor control is its steps from the Angle of 3 -5% and not cumulative, its speed is proportional to the pulse frequency, also, that is, the higher the frequency the faster the speed, high velocity, acceleration is too big, cause sometimes & other; Throw the step & throughout; And then lead to motor & other; Jammed & throughout; ； After the servo motor control precision of the motor shaft rotary encoder resolution. Encoder calibration accuracy is higher, the more servo motor for closed loop control system, can he received & other; Electrical & throughout; Through motor internal transformation again by the encoder feedback to drive, drive directly on the motor feedback signal sampling, generally do not render stepper motor & other; Throw the step & throughout; Or & otherOvershoot & throughout; Phenomenon, more stable function. 2. If the stepper motor control wrong will attack & other; Resonance & throughout; Also is the low speed oscillation phenomenon, let's say working motor show & other; Oscillation & throughout; The motor is very bad; And the communication of the servo motor servo control system has a resonance suppression function, so that even at low speeds not present resonance phenomenon. 3. Stepper motor output torque will follow high speed decreases, and the higher the speed down faster, servo motor is constant torque output, torque will not follow speed decreases increased, and the constant power output in the rated speed. 4. Servo motor has strong withstand overload ability, able to overcome the load inertia moment start torque, stepper motor often do not have such talent, so should choose inertia moment when selecting larger models, but often it is not. Servo motor on the function is better than that of step motor, the stepper motor wiring, programming a brief, less trouble, torque also is enough big, stepper motor can achieve 6000 pulse, highest speed 3000 RPM, general stepping motor also can reach 600 RPM, the speed will be enough for some of the common equipment, so the selection of cutting machine when choosing control systems and equipment to the selected drive motor into consideration, if you split the requirements of the machine is not high word just as well to consider stepping motor, step motor and servo motor price difference, after all, is not a bit, reasonable selection, cost control, economical and practical.
