Stepper motors are used to convert electrical power to mechanical power. Hence they are electro mechanical devices. They contain numerous coils ordered in groups known as 'phases. The motor rotates step by step by energizing each phase sequentially. One can achieve speed control and precise positioning by computer-controlled stepping. These Closed Loop Stepper is available in various styles and sizes with varying electrical properties.
Characteristics of a high torque stepper motor-
Speed control: One can acquire excellent control of the rotational speed by precise increments in the movements. It has a lot of scope in robotics and automation processes.
Positioning: These motors are extensively used in applications like CNC, 3D printers, X-Y plotters, Camera platforms, and much more due to their precise, repeatable steps. Disk drives also use motors to position their read/write heads.
Low-speed torque- the regular DC motors do not possess much torque at low speeds, but a stepper motor has an exceptionally maximum torque even at low speeds. Hence, they are a perfect choice for applications requiring low speed and high precision.
The general stepper motors have a different operation than DC brush motors which are capable of rotating when a voltage is applied at their terminals. Whereas these motors effectively contain multiple electromagnets around a gear-shaped central piece of iron in a tooth-like arrangement. These electromagnets are excited by using an external control circuit like a micro controller. You can easily Buy Stepper Motor at the best market price.
