Problems solved by technology

However, the use of sensors increases the cost of the system on the one hand, and the price of some high-precision sensors even occupies a major share of the cost, while the increase in system volume limits its application in limited space, and the sensor requires high installation accuracy; on the other hand On the one hand, the reliability of the system is reduced, and the increase of wires between the motor and the control system makes the system susceptible to external interference, and its accuracy is easily affected by ambient temperature, humidity, dust, vibration, etc. Therefore, for high temperature, high humidity, dusty The working environment of textile motors, the application of motor systems with sensors is limited
