Jkongmotor Linear Stepper Motor with Linear Guide


1. Overview of linear screw stepper motor:

The stepper motor with linear screw guide uses a hybrid stepping motor as the power source. Through the unique patented technology, the threaded transmission component and the motor rotor are combined together to convert the rotary motion of the motor into linear motion.

Changzhou Jkongmotor Co., Ltd. produces a new avenue for those who need to design equipment with high performance and excellent durability in a very small space. Various patented designs and the use of a proprietary production method incorporating engineering thermoplastics into the rotor drive nut, in conjunction with the use of stainless steel Acme threaded guide rods, makes the motor quieter than other motors using V-thread and bronze nut construction , efficient and durable. Motor life is more than 10 times longer than the commonly used bronze nut construction, and it requires no maintenance without compromising cost. Another feature is that the preload adjustment does not protrude outside the motor like other designs.

The products currently on the market of Jkongmotor are: 20mm series, 28mm series, 35mm series, 42mm series, 57mm series, 86mm series two-phase hybrid linear stepping motor. Products cover a variety of different step sizes, from 0.003048mm to 0.127mm microsteps, providing uniform and fine resolution. There are three structures for each frame size: through shaft type, external drive type, and fixed shaft type.

Second, the linear screw stepper motor features:

● High precision, positioning accuracy up to ±0.02mm

The linear screw stepping motor reduces the problem of interpolation lag due to the simple transmission mechanism. The positioning accuracy, repeatability and absolute accuracy are generally higher than that of "rotary servo motor & ball screw", and it is easy to implement. The positioning accuracy of the linear screw stepping motor can reach ±0.02mm, and the "rotary servo motor ball screw" can reach the maximum ±0.01mm.

● High speed, up to 300m/min

In terms of speed and acceleration, the linear screw stepping motor has considerable advantages. The linear screw stepping motor has a speed of 300m/min and an acceleration of 10g; the ball screw has a speed of 120m/min and an acceleration of 1.5g. . Moreover, the speed of the linear screw stepping motor will be further improved after successfully solving the heating problem, while the "rotary servo motor & ball screw" is limited in speed and it is difficult to increase it any further.

● Long life and easy maintenance

The linear screw stepping motor has no contact between the moving parts and the fixed parts, and will not be worn due to the high-speed reciprocating motion of the mover. The long-term use does not change the positioning accuracy of the movement, and is suitable for high-precision occasions. The ball screw cannot guarantee the accuracy in high-speed reciprocating motion. Due to high-speed friction, the lead screw nut will be worn, which will affect the accuracy requirements of the movement, and cannot meet the needs of high-precision.

3. Application fields of linear screw stepper motor:

Linear stepper motors are suitable for applications requiring precise positioning, fast movement and long life. Typical applications include X-Y tables, medical equipment, semiconductor processing, communication equipment, modulation valves, printing equipment, environmental protection equipment, automatic robots, 3D printers, etc.
