All About Stepper Motor

A stepper motor is a type of brushless DC electric motor that moves in precise angles, called steps, by converting a series of electrical pulses into rotational motion. They will not produce continuous motion from a continuous input voltage, and it will stay at a particular position as long as the power is “on”.

Step motors are controlled with the use of discrete electrical pulse signals. Each pulse will rotate the step motor shaft by a fixed angle called a “step”. ISL Products can offer stepper motors with several different step angles (0.45°, 0.9°, 1.8°). ISL offers a concierge approach, ensuring that our Stepper Motors perform as intended within your application.

If the pulses are carried out in a specified sequence, the motor will spin continuously; the speed can be controlled by the rate at which the pulses are sent.

These natural step angles allow a step motor to be accurately positioned without the accumulation of error. The step motor produces output torque from the interaction between the magnetic field in the rotor and in the stator. The magnetic field strength is proportional to the amount of current applied to the windings as well as the number of turns in the windings.

Stepper motors fill a unique niche in the motor control world. These motors are commonly used in measurement and control applications throughout various industries. Sample applications include Ink Jet Printers, CNC machines, 3D Printers, Automation & Packaging machines, Security & Surveillance systems, Medical Tools & Equipment, Robotics, and Vending machines.

Determining Which Motor is Right For You

Determining which type motor you need may not be an easy task. There are many different types available today. Before you order, there are a number of parameters that need to be addressed. So how can you properly accomplish this? This article is written to assist you in determining which motor is best for your application.

First and foremost you will need to know what voltage source is available in your application. Electric motors can be classified as either AC (Alternating Current) or DC (Direct Current). Alternating current types only run on AC Voltage and direct current types only run on DC Voltage. There is also a universal motor that can run on both AC and DC voltages.

Once you have established which power source you have you will need to determine which style will work for your application. AC motors can be sub-divided into the following: Single Phase Induction, Three Phase Induction, Two Phase Servo, and Hysteresis Synchronous. DC motors can be sub-divided into: Brushless DC, Brush DC, and Stepper types.

Next we need to understand the different characteristics of each type in order to properly match a motor to its application.

A single phase induction motor is connected to a single voltage line. An external capacitor is required to make this motor operate. The different types of single phase induction motors are distinguished by which method they are started. The four basic types are: split phase, capacitor start, permanent split capacitor, and capacitor start/capacitor run.
