Lifting platform stepper motor is the working principle and advantages

点击浏览: Release time: 2018-03-28Click to browse: Source: Longzhu Machinery- Lift Freight Lift Manufacturer
The platform stepper motor is an electrical device. The rotation of the motor is divided into separate parts, called stepper motors. Generally, these motors are brushless to facilitate synchronous rotation and operation without the need for an external source of the gear itself. They use electromagnets to arrange their shafts in different places for each tooth. These teeth match the teeth and are placed on the gear itself. When the gear of the lifting platform rotates, a part of the matching electromagnet is used to offset the teeth from the other electromagnets and repeat this operation.





The general principle of a stepper motor is to rotate to a specific stage each time. By turning the electromagnet on and off, the phase control of the stepping motor of each lifting platform is repeated. This means that with different direct current (DC) motors, controlled by brushes and voltage, the elevator platform only needs to be charged when entering the motor shaft itself.

In the equipment design, there are three kinds of stepper motor control mechanisms. One format is to control the electromagnet with a permanent magnet located in the inner rotor by creating a hydraulic lifting gear that attracts and repels. The other uses of the magnetic shaft itself are essentially pulling the gear onto the opposite shaft in the opposite way. Another design is a technology that combines the magnetic response of gears and shafts.

Some negative characteristics of stepper motors are very unique in the field of motion control. First, a stepper motor drive requires a constant power source. In addition, the gear of the physical device decreases with the increase of the gear rotation speed. This creates a state where the motor starts to vibrate, and this state can only be controlled by increasing the damping of the shaft itself. One way to mitigate this overall effect is to add more electromagnetic systems, increase the number of steps, and reduce vibration.
