Linear sliding platform linear motor is a device that integrates linear motor and sliding platform. It combines the precise control of linear motors and the smooth movement of sliding platforms to achieve precise positioning and orientation of linear motion. The following is a more detailed description of the linear sliding platform linear motor:
Construction and Working Principle: The linear sliding platform linear motor consists of a linear motor and a sliding platform. A linear motor is usually located at the bottom of a sliding platform, which is located on a bracket. The motion of a linear motor generates linear motion along an axis, which allows the sliding platform to slide smoothly on that axis.
Features:
1. High precision: The linear sliding platform linear motor has high-precision position control capability, suitable for applications that require precise positioning.
2. Smooth motion: The motion of the linear motor provides smooth and continuous power, allowing the sliding platform to move at a stable speed, thereby reducing vibration and impact.
3. No transmission components:Due to the use of linear motor technology, traditional transmission components (such as gears or belts) are not required, thereby avoiding mechanical losses and vibrations during the transmission process.
4.Quick Response: Linear motors have the characteristic of fast response and can complete motion commands in a short time, suitable for applications that require fast positioning and variable speed motion.
5. Customization: The linear sliding platform linear motor can be customized according to application requirements, including axial length, load capacity, and control system.
What are linear motors?
Linear motors are electric induction motors that produce motion in a straight line rather than rotational motion. In a traditional electric motor, the rotor (rotating part) spins inside the stator (static part); in a linear motor, the stator is unwrapped and laid out flat and the "rotor" moves past it in a straight line. Linear motors often use superconducting magnets, which are cooled to low temperatures to reduce power consumption.
Artwork: Top: Normal motor: The rotor spins inside the stator and the whole motor is fixed in place. Bottom: A linear motor is like a normal electric motor that has been unwrapped and laid in a straight line. Now the rotor moves past the stator as it turns.
How linear motors work?
In a traditional DC electric motor, a central core of tightly wrapped magnetic material (known as the rotor) spins at high speed between the fixed poles of a magnet (known as the stator) when an electric current is applied. In an AC induction motor, electromagnets positioned around the edge of the motor are used to generate a rotating magnetic field in the central space between them. This "induces" (produces) electric currents in a rotor, causing it to spin. In an electric car, DC or AC motors like these are used to drive gears and wheels and convert rotational motion into motion in a straight line.
