Stepper motors are brushless
Ron Hextall Flyers Jersey , synchronous electric motors that convert digital pulses into mechanical rotation. Due to rugged construction, high reliability, high torque at low speeds, and their lower
Every revolution of a stepper motor is divided into a discrete amount of measures. Typically an individual turning is 200 measures or 1.8 degrees of rotation per step. Each step is the same size, and since a stepper motor can only just take one step at a time, the position of the motorcan be controlled without feedback. Clearly, as the pulsation frequency increases the discrete measure movement will change with the rate directly proportional to the pulsation frequency - into continuous rotation.
Types of Step Motors
You can find three basic types: variable reluctance
Michael Raffl Flyers Jersey , permanent magnet, and hybrid. Hybrid motors combine the finest characteristics of the other two kinds. They are built with a permanent magnet rotor and toothed stator poles. Standard hybrids have 200 rotor teeth and rotate at 1.8 degrees per step. Winding connection stepper motor windings may be connected in parallel or series. Sequence connection provides greater torque at low speeds. Concurrent connection lowers the inductance providing increased torque at speeds that are quicker. The main advantage of steppers over DC Motors (Gleichstrommotoren) or DC Gearmotors (Getriebemotoren) is that they are able to react much faster without increasing the current.
