The 23Y Series High Torque Stepper Motors offer a great value without sacrificing quality. These motors are designed to offer the highest possible torque while minimizing vibration and audible noise. A broad line of motor windings and stack lengths are available off-the-shelf. Low Efficiency – Unlike DC motors, stepper motor current consumption is independent of load. They draw the most current when they are doing no work at all. Because of this, they tend to run hot. Limited High Speed Torque - In general, stepper motors have less torque at high speeds than at low speeds. Some steppers are optimized for better high-speed .
The holding torque is the amount of torque the motor shaft can produce while stationary with full rated current flowing in both phases of the 2-phase stepper motor’s windings Holding torque is one of the primary specifications for any stepper motor. Here is a typical chart showing holding torque and detent torque versus position. There are several different stepper motor technologies including permanent magnet motors, variable reluctance, and hybrid types. The principle of operation for stepper motors is fairly straightforward. Traditional variable reluctance stepper motors have a large number of electromagnets arranged around a central gear-shaped piece of iron.

For more information on stepper motors, please visit the "Stepper" page in the Wikibook of Electric Motors and Generators. For this book, we will just look at the basics.
There are two kinds of stepper motor - unipolar and bipolar. Bipolar motors are the simplest, so we will look at those first.
Bipolar Motors. By energizing each phase in sequence, the motor will rotate, one step at a time. With a computer controlled stepping you can achieve very precise positioning and/or speed control.
For this reason, stepper motors are the motor of choice for many precision motion control applications. Stepper motors come in many different sizes and styles and File Size: 2MB.
A stepper motor is different again. This time, the permanent magnets are on the inside and rotate (making up the rotor), while the coils are on the outside and stay static (making up the stator). The third big difference between an ordinary DC motor and a stepper motor is in the design of the stator and the rotor.

Each of these steps is defined by a Step Angle. In the example above you may notice that there are 4 distinct steps for the rotor to make a complete degree rotation. This defines the step angle at 90 degrees.
Since this motor does move in a discreet fashion. A stepper motor moves one step when the direction of current flow in the field coil(s) changes, reversing the magnetic field of the stator poles. The difference between unipolar and bipolar motors lies in the way that this reversal of the magnetic field is achieved (Figure 1).
The bipolar motor has one coil per phase and needs two changeover. Inside a Stepper Motor There are several designs of stepper motors.
For the time being, we’ll concentrate on the most popular variety, the four-phase unipolar stepper, like the one in Fig.
A unipolar stepper motor is really two motors sandwiched together, as shown in Fig. Each motor is composed of two windings.
Stepper Motor vs Servo Motor. A stepper motor is a “digital” version of the electric motor. The rotor moves in discrete steps as commanded, rather than rotating continuously like a conventional motor. When stopped but energized, a stepper (short for stepper motor) holds its load steady with a holding torque.

Stepper motors are the workhorses of the motion industry, giving designers numerous degrees of freedom to live up to choose the exact right motion source for their application. By understanding the nuances of the various drive wiring schemes, you can find a stepper motor that support your requirements at a price you like.
A stepper mottor is a brushless, synchronous electric motor that converts digital pulses into mechanical shaft rotation. Every revolution of the stepper motor is divided into a discrete number of steps, in many cases steps, and the motor must be sent a separate pulse for each step.
The invention of dedicated stepper motor driver cards and other digital control technologies for interfacing a stepper motor to PC-based systems are the reason for the widespread acceptance of stepper motors in recent times.
Stepper motors become the ideal choice for automation systems that require precise speed control or precise positioning or both. Motor Knob: Control a highly accurate stepper motor using a potentiometer. Stepper One Revolution: Turn the shaft one revolution clockwise and one counterclockwise.
Stepper One Step At A Time: Turn the shaft step by step to check the proper wiring of the motor. Stepper Speed Control: Control the stepping speed with a potentiometer.
Last. Stepper motor is a special type of electric motor that moves in precisely defined increments of rotor position (Steps). The size of the increment is measured in degrees and can vary depending on the application.
Due to precise control, stepper motors are commonly used in medical, satellites, robotic and.

This translate to FULL steps per revolution (1 rotation = degrees | / = ) Now when using FULL steps, the rotation of the stepper motor can be quite choppy, especially at lower speeds. The Easy Driver support of course FULL steps per default, but like we saw above also.A stepper motor is a brushless, synchronous electric motor that converts digital pulses into mechanical shaft normal shaft motion consists of discrete angular movements of essentially uniform magnitude when driven from sequentially switched DC power supply.
The stepper motor is a digital input-output device.
