1. Hybrid Linear Stepper Motors Overview
Hybrid linear stepper motor is a new linear movement executive motion control product, converting the round rotation movement into linear movement.
The hybrid linear stepper motor is composed of driving motors, deceleration gears, screws, nuts, guides, push rods, slides, spring, shells and turbine, micro -control switch, etc.
Generally, the standard stroke of the electric screw is 100,150, 200, 250, 300, 350, 400mm, while special stroke requirements can be supported by flexible customization. The hybrid linear stepper motors can be designed with different thrust screw leads according to different application loads.
The maximum thrust of the hybrid linear stepper motors can reach up to 20kN, the without load speed normally is 4 ~ 45mm/special linear speed can also be customized.
The use of hybrid linear stepper motor as an execution agency can not only reduce the gas/liquid source device and auxiliary equipment required to use pneumatic and hydraulic pressure, but also reduce the weight of the execution agency.
Hybrid linear stepper motor features,
- High accuracy: Because the screw rod is a spiral line, the stepping motor with a drive can make the position accuracy high, usually 0.01 mm.
- Large torque: The torque of the stepping motor with a screw drive is relatively large, which can withstand large loads and inertia.
- Simple structure: The transmission structure of the screw is simple, and there is no need to specialize in a dedicated deceleration mechanism. The cost is low.
- Lack of resistance to interference: Since the stepper motor controls the discrete signal, it has a small impact on environmental interference.
- Convenient control: Step motor with a drive can achieve efficient control by programming and high degree of automation.
Hybrid linear stepper motors are widely used in automation applications, such as electronic production machines, semiconductor producing, medical equipment’s, testing platforms, factory automation, etc.
