Closed loop stepper servo motor

Product advantages

Compared with traditional stepper products, closed-loop stepper servos do not experience step loss, ensuring precise motor positioning and improving high-speed performance by about 30%. They also increase equipment operating speed, reduce heat generation by 20% during normal motor operation, alleviate torque reduction, significantly reduce motor vibration, and run more smoothly. Variable current control technology is adopted to save energy consumption.

2. Compared with traditional AC servo products, closed-loop stepper servo does not require complex parameter adjustments, is more convenient to use, does not shake when stopping at high speed, has stable zero speed stop, and has extremely fast position response. It is particularly suitable for short distance fast start stop situations, with a cost reduction of more than 50%, larger torque, and smaller installation size.

Product Features

1. Closed loop control technology, like AC servo systems, does not lose step. Installing a position encoder enables the motor to have the closed-loop characteristics of a servo motor, fundamentally solving the problem of step loss in traditional stepper motors.
2. Significantly improve the high-speed performance of the motor. It can increase the effective torque of the motor by more than 30%.
3. Effectively reduce the heat generation of the motor. The output current of the driver increases and decreases with the increase of load and speed.
4. Shorten the corresponding time for motor acceleration and deceleration. The output and input commands of position response are almost synchronized in real time, making it very suitable for applications such as short distance fast start stop and zero speed stable stop.
5. There is no oscillation when the motor brakes. The closed-loop stepper servo drive system has the unique holding torque characteristic of stepper motors, which can stably reach the set position and avoid oscillation.
6. The motor runs more smoothly and has higher accuracy. Adopting the most advanced dedicated motor control DSP chip, applying vector control and smoothing filtering technologies to achieve smooth motion control of stepper motors.
7. No gain adjustment required, very convenient to use. The closed-loop stepper servo system combines the convenience of using stepper motors with the reliability of servo systems, making it easy to use without the need for tedious parameter tuning.

Application field

At present, Skyworth stepper motor products have been widely used in automation equipment such as engraving machines, laser machines, CNC machine tools, medical equipment, electronic processing equipment, textile and clothing machinery, etc.
