YK-KE-146 835N High Precision Semi-Enclosed Linear Motor Modules High Performance Quality For Industrial Automations
1. Products Overview
Direct drive linear motor (referred to as linear motor) is a device
that directly completes linear transmission. It can directly
replace the mechanical transmission parts, such as ball leadscrew,
rack and pinion, belt/ pulley, etc., to greatly reduce the
transmission clearance and the noise, wear, vibration and other
related problems caused by mechanical transmission. The essence of
linear motor
transmission is to spread the rotating motor stator and rotor
horizontally, and directly connect to drive the load. Linear motor
is characterized by high transmission efficiency and good dynamic
response. Linear motors are widely used with the development of
industrial automation and the equipment requirements being
stricter.
The linear motor is often briefly described as the rotary motor is flattened, and the working principle is similar. The Rotor is made of compressing coils with epoxy materials; magnetic tracks are fixed on steel plane. The Rotor of the motor includes coil winding, Hall component circuit board, electric heating regulator (temperature sensor monitoring temperature) and electronic interface. In regular rotating motor, the movement of the rotor and the stator need bearings’ support to keep proper air gap. Similarly, the linear motor needs a linear guide to maintain the position of the movement generated by the Rotor in the magnetic field. The linear motor needs to feedback the position of the Rotor by a linear encoder, which can directly measure the position of the load to improve its position accuracy.
Compared with the rotating motor, the linear motor mainly has the following characteristics:
Applications:
Kaifull linear motors are widely used in industrial automation applications, such as semiconductor assembly, photoetching machinese, laser machines, wafer detection, AOI, electronics assembly, precise dispensing, medical treatment, PCB puching, textile machines, Digital inkjet priting, intelligent sorting, luggage transport, high speed laminating equipment, food processing, coordinate measuring, precison grinding, wire cutting, ultra-high speed machines etc.
2. Products Features
Simplify Complex Processes, Module Forming:
Breaking the traditional linear motor, it is composed of complex and multi component components. The base and guide rail are integrated, and the slider, slide plate, and reading head bracket are integrated to form a simple and sturdy integrated module.
Ultra-High Precision, Perpetually:
By employing a specialized process to embed guide rails directly
into aluminum profiles, followed by a single-pass precision
grinding using high-precision grinding machines, the linear motor
achieves even higher
accuracy and enhanced durability.
More Oil Storage, Longer Operation:
With a large oil storage capacity, the largest module can run up to 100,000 kilometers on a single oil injection.
Higher Load Capacity, Steadier Operation:
The slider contains a substantial number of large precision steel balls, each ball capable of bearing a load of 1 to 2 tons.
Unwavering in Harsh Applications:
Capable of withstanding a 500mm eccentric load, the module continues to operate impeccably.
Optimized Material for Enhanced Wear and Rust Resistance:
The embedded guide rails are made from stainless steel material, offering superior resistance to wear, corrosion, and rust.
