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 […]


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 […]

Wound Rotor Induction Motor with Subsynchronous Converter Cascade

Wound Rotor Induction Motor with Subsynchronous Converter CascadeĀ in the Rotor Circuit: The following points favour the application of a slip ring motor having static slip energy recovery scheme in the Subsynchronous Converter Cascade circuit, to drive a centrifugal pump (Fig. 7.10). 1.The delivery rate control of the pump is accomplished by speed control of the […]
