Common Aspects Between Generators and Motors

Leave a Comment / Generators, Motors / Engr. Aneel Kumar

Introduction Synchronous generators and motors share many theoretical and operational similarities, making it essential to understand their common aspects. These machines are pivotal in industrial applications, particularly in the oil and gas sector, where their reliability and efficiency are critical. Theory of Operation Both synchronous generators and motors operate based on the same fundamental principles. […]

COMPARISON OF SQUIRREL CAGE AND SLIP RING MOTOR

Leave a Comment / Alternating Current, Electrical Machines, Motors / Engr. Aneel Kumar

A wound-rotor motor (Slip Ring Motor) is a type of induction motor where the rotor windings are connected through slip rings to external resistances. Adjusting the resistance allows control of the speed/torque characteristic of the motor. Wound-rotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit; as the

STEPS TO BETTER MOTOR APPLICATIONS

1) KNOW THE LOAD CHARACTERISTICS For line-operated motors, loads fall into three general categories: constant torque, torque that changes abruptly, and torque that change gradually over time. Bulk material conveyors, extruders, positive displacement pumps, and compressors without air unloaders run at relatively steady levels of torque. Sizing a motor for these applications is simple once

MOTOR A motor is an extended version of a transformer. Here we can introduce the analogy between a transformer and a motor that is a motor is like a transformer with a moving secondary. The primary that is not moving is called stator and the secondary that is moving is called rotor. The type of

(1) By using a starting motor. This motor is directly coupled to the motor. It may be an induction motor which can run on a synchronous speed closer to the synchronous speed of the main motor. (2) Starting as an induction motor. This is the most usual method in which the motor is provided with
