Peak torque induction vs wound field

WebAug 24, 2024 · Asynchronous (induction) motors can be further categorized into two different types based on their construction: the squirrel cage induction motor and the wound rotor induction motor. Synchronous and asynchronous motors are both 3-phase motors, however, they operate on different principles. Images adapted and used courtesy of ABB. WebThere are several types of motor. Motors with internal permanent magnets (IPMs) and surface permanent magnets (SPMs) can make use of the reluctance between the rotor and the magnets to boost the torque, while induction motor (IM) and wound field synchronous machine (WFSM) designs offer different trade-offs between power, torque and axle speed.

WebDec 29, 2015 · In a DC shunt motor, torque is proportional to armature current (as shown in the torque equation below). In contrast, for a series-wound DC motor, torque increases as the square of armature current. This exponential torque-current relationship allows series-wound DC motors to provide high starting torque and handle high startup loads. WebAug 30, 2024 · In most aspects, the series wound DC motor is similar to other forms of brushed DC motors in structure and performance. It is composed of two vital parts, the rotor and stator, which interact magnetically and electrically to create rotational movement on an output shaft. The main structure of DC motors is comparatively simple, and a simplified ...
