Linear motor is also called U-shaped slot linear motor. It consists of stator high-density magnetic steel and stator inner coil. It has uniform magnetic steel, large magnetic flux and no loss. Its inertia is small, response is fast, speed is high, acceleration High for high speed reciprocating motion and high acceleration motion. It has the characteristics of high response, large thrust, zero backlash, high precision, simple structure and mechanical structure design. It is a favorite of European and American technical standards. Linear motor standard U-type linear motor has peak thrust. 2600N, continuous thrust up to 750N, its positioning accuracy can reach less than 0.5UM.
The linear motor drive system is closed-loop control. The drive can directly sample the motor encoder feedback signal. The internal position loop and speed loop are formed. Generally, the stepper motor loses or overshoots, and the control performance is more. To be reliable.
Before the linear motor starts, it is necessary to know the relative position of the rotor and the stator to use the sensor. The non-inductive motor directly measures the back electromotive force of the motor and knows the position of the rotor. The controller drives the power tube to perform the high-speed development of the commutation drive technology and the automatic control technology, and the performance of the linear motor is getting better and better. Direct drive brushless linear motor is quiet, noise-free, maintenance-free, long life, high precision and high rigidity. Linear motor.
