The basic performance and principle of lead screw linear motor, with the continuous development of science and technology, the supply of motors is increasing, and many economic fields involve motors, and is widely used in various automatic control systems. Today, we have the honor to invite experts in lead screw linear motor to introduce the basic performance and principle of lead screw linear motor. Let's take a look at the details! The motor is an actuator that converts electrical pulses into angular displacements. Generally speaking, when the stepper motor driver receives a pulse signal, it drives the stepper motor to rotate at a fixed angle in the set direction. The angular displacement can be controlled by controlling the number of pulses, thus achieving the purpose of accurate positioning; At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thus achieving the purpose of speed regulation. Generally, the rotor of a precision sliding screw stepping motor is a permanent magnet. When current flows through the stator, the stator generates a vector magnetic field. The magnetic field will drive the rotor to rotate at an angle, so that the direction of a pair of magnetic fields of the rotor is consistent with the magnetic field direction of the stator. When the stator's vector magnetic field rotates an angle. The rotor also rotates an angle with the magnetic field. Every time an electric pulse is input, the motor rotates one angle to advance one step. Its output angular displacement is proportional to the number of input pulses and its rotation speed is proportional to the pulse frequency. Change the order of the winding power, the motor will reverse. Therefore, the rotation of the stepping motor can be controlled by controlling the number and frequency of pulses and the power-on sequence of each phase of the motor. In view of the introduction of the above article, everyone should understand the basic performance and principle of the lead screw linear motor.
