1. Hybrid Linear Stepper Motor
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.
Applications:
The application of hybrid linear stepper motor is very wide, including the followings,
The performance characteristics:

7. Faults Checking
During use, there may be some faults in the hybrid linear motors. Common faults include strolls, excessive noise, and overheating. The loss may be caused by insufficient motor resolution and mechanical transmission error. It can be solved by adjusting the subdivision of the motor -driven signal. Excessive noise is likely to be caused by high motor speed and mechanical resonance. It can be eliminated by reducing the speed of the motor and adjusting the mechanical structure. Excessive heat may be caused by the long -term work and poor heat dissipation, which can be improved by strengthening heat dissipation and reasonable arrangement.
