Stepper Motor Classification

Stepper Motor Classification: The Stepper Motor Classification based on the construction and principle of operation. These are Variable reluctance motors Permanent magnet motors Hybrid stepping motors Claw pole motors with permanent magnets The stepper motors are used for linear motors also. These are also classified as ‘variable reluctance motors’ and ‘permanent magnet motors’. Variable Reluctance […]

Features of Stepper Motor

Features of Stepper Motor: The Features of Stepper Motor are small step angle high positioning accuracy high torque to inertia ratio stepping rate and accuracy Small Step Angle: The angle by which the rotor of a stepper motor moves when one pulse is applied to the (input) stator is called step angle. This is expressed […]

Stepper Motor Applications

Stepper Motor Applications: The microprocessors are employed for the control of stepper motors which are generally used as position actuators. Some other Stepper Motor Applications are to drive floppy discs, numerical control of machine tools, X-Y plotters etc. The ease with which these can be controlled using microprocessor has made them very popular in the […]

Turbocompressors

Turbocompressors: The turbocompressors and blowers in the industry require drives rated up to 40 MW. Drives of large rating are also required in steel industry blast furnace blowers in natural gas pipelines and liquefaction processes in wind tunnels chemical process industry. In the upper power range a converter fed synchronous motor is a suitable drive […]
