Nema 34 2 Phase Brake Motor 8.7N.M CE ROHS Approved For Cnc Machine
Nema34 8.7N.m Stepper Motor With Brake For Cnc Machine CE ROHS Approved
The combination of two motors like a permanent magnet and variable reluctance is known as a hybrid motor. The working principle of a hybrid motor is, the rotor in this motor is magnetized axially similar to a permanent magnet stepper motor, whereas the stator is energized electromagnetically similar to a variable reluctance stepper motor. So it is an actuator that changes electrical pulses to angular displacement.

Advantages of Hybrid Stepper Motor
The advantages of the Hybrid Stepper Motor are as follows:-
The length of the step is smaller.
It has greater torque.
Provides Detent Torque with the de-energized windings.
Higher efficiency at lower speed.
Lower stepping rate.
Stepper Motor Applications
- As the stepper motor are digitally controlled using an input pulse, they are suitable for use with computer controlled systems.
- They are used in numeric control of machine tools.
- Used in tape drives, floppy disc drives, printers and electric watches.
- The stepper motor also use in X-Y plotter and robotics.
- It has wide application in textile industries and integrated circuit fabrications.
- The other applications of the Stepper Motor are in spacecrafts launched for scientific explorations of the planets etc.
- These motors also find a variety of commercial, medical and military applications and also used in the production of science fiction movies.
- Stepper motors of microwatts are used in the wrist watches.
- In the machine tool, the stepper motors with ratings of several tens of kilowatts is used
