What is a linear stepper motor?
Linear stepper motor is a special type of stepper motor , whose design and working principle are different from traditional rotary stepper motors. A linear stepper motor is a type of linear motor that achieves linear displacement through linear motion, rather than the rotational motion achieved by traditional stepper motors.
Working principle:
The construction of a linear stepper motor usually consists of a fixed stator and a movable slider. The stator is equipped with a coil inside, while the slider is equipped with a permanent magnet. When current passes through the stator coil, a magnetic field is generated . The interaction between the permanent magnet on the slider and the magnetic field of the stator generates attraction or repulsion, resulting in linear motion of the slider on a fixed axis.
Control method: Controlling a linear stepper motor is similar to a traditional stepper motor, where the position and speed of the slider can be controlled by controlling the direction and magnitude of the current. The pulse signal of each stepper motor causes the slider to move a fixed step distance, which can achieve precise linear displacement.Application: The application research of linear motors, as an important part of linear motor research, is also the ultimate goal of studying linear motors. Due to the fact that linear motors do not require any transmission devices and can directly generate continuous unidirectional or reciprocating linear motion, they have broad application prospects.
The application of linear motors in the manufacturing industry relies on screw drives for traditional machine tools. The screw drive itself has a series of unfavorable factors such as friction, distortion, and long vibration attenuation time, which limits the efficiency and accuracy of traditional drive devices Linear motor drive technology has high efficiency, precision, and simple structure that traditional drive devices cannot match.
Compared with traditional rotary motor driven electric locomotives, linear motor driven locomotives have many advantages such as low cost, low vibration, low noise, strong climbing ability, superior traction ability, small curve radius, low energy consumption, low pollution, and good safety performance. Linear motor has a wide application prospect in the transportation industry.
The application of linear motors in ocean power generation:
Wave energy generation is a typical representative of the application of linear motors as generators. Wave energy refers to the kinetic energy and potential energy possessed by ocean surface waves, and is the most unstable type of energy in ocean energy. The linear motor wave energy device does not rely on mechanical or hydraulic conversion devices, resulting in higher efficiency.
