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.
