Hybrid Stepper Motor Applications

The word hybrid means combination or mixture.

Hybrid stepper motor applications.

While these three vary in their operation each brings a number of advantages to certain applications over their servo motor counterparts. Hybrid stepper motors are named because they use a combination of permanent magnet pm and variable reluctance vr. Variable reluctance vr motors have a plain iron rotor and operate based on the principle that minimum reluctance occurs with minimum gap hence the rotor points are attracted toward the stator magnet poles. These motors are applicable in the production of automated devices gauges machines used as cutting labeling packaging filling etc.

A hybrid stepper motor or a hb stepper motor is a combination of the features of the variable reluctance stepper motor and permanent magnet stepper motor the shaft of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. These are used in lane diverters elevators and conveyor belts. The main types of stepper motors include permanent magnet stepper motors variable reluctance stepper motors and hybrid synchronous stepper motors. A stepper motor also known as step motor or stepping motor is a brushless dc electric motor that divides a full rotation into a number of equal steps.

The motor s position can then be commanded to move and hold at one of these steps without any position sensor for feedback an open loop controller as long as the motor is carefully sized to the application in respect to torque and speed. Although linear stepper motors are available in both variable reluctance and hybrid designs the more common version is hybrid linear stepper motors. Hybrid synchronous stepper motor.
