Nema23 Stepper Motor With Brake High Torque Stepping Motor 1.89N.m 26 oz.in 57HT76-2804
Applied Motion Products is pleased to announce the release of holding brakes for select step motors in the NEMA 23 frame size. These step motors provide additional functionality for applications which require holding torque to be maintained when power is removed from the motor.
Holding brakes offered by Applied Motion are spring-set type brakes that must be powered by 24 volts DC to release the brake mechanism. This is commonly referred to as “power off” and is the preferred style for motion control applications. Controlling the brake is handled by a discrete output on the stepper drive or another controller like a PLC or motion controller. Many Applied Motion drives offer outputs specifically designed to control the holding brake, such that the brake will be automatically engaged whenever the motor is unpowered (and automatically disengaged when the motor is powered or moving).

The advantages of the Hybrid Stepper Motor are as follows:-
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.
