· A typical DC motor consists of an outer, permanent magnet stator and an inner rotor made of iron laminations with windings. Coreless DC motors do away with the laminated iron core in the rotor. Instead, the rotor windings are wound in a skewed, or honeycomb, fashion to form a selfsupporting hollow cylinder or "basket.".
· The Yaesu "Gseries" rotors use DC on the motor, not AC. There is no starting capacitor in the control box. Motor reversal, in the G450, is accomplished by switching the DC current from 1side of the motor winding to the other. The "common" for this voltage is applied to a centertap on the winding and then, when the voltage is applied to 1 ...
· Construction of AC Motors. The 3phase induction motor mainly consists of two parts: Stator. Rotor. The stator is a static part and rotor is a rotating part, both are separated by a small air gap, which varies from mm – 4 mm depending on the rating of the motor. 1.
Stepping Motors ORIENTAL MOTOR GENERAL CATALOG 2012/2013 G40 Structure of Stepping Motors The figures below show two crosssections of a ˚ stepping motor. The stepping motor consists primarily of two parts: a stator and rotor. The rotor is made up of three components: rotor 1, rotor 2 and a permanent magnet.
Axial motors have been used for some time for lowpower lowcost brushless DC motors, since the motor can easily be built directly upon a PCB, or even using PCB traces as the stator windings, but recently there have been more efforts to design highpower brushless motors in an axial geometry. A successful brushed DC axial motor is the Lynch motor, where the rotor is almost entirely composed .
Cogging torque of electrical motors is the torque due to the interaction between the permanent magnets of the rotor and the stator slots of a Permanent Magnet (PM) machine. It is also known as detent or 'nocurrent' torque. This torque is position dependent and its periodicity per revolution depends on the number of magnetic poles and the number of teeth on the stator.
Induction motors. GE's induction motor technology –medium power and large power– delivers high reliability and efficiency, primarily by drastically reducing the rotor's parts. It means a leaner, lower maintenance motor that consistently delivers the power you need. With the recent advances of GE's high powered, variable frequency drives, induction motors (medium power and large power) can ...
direction. With the rotor position as shown, suppose the stator poles are at that instant situated at points A and B. The two similar poles, N (of rotor) and N S (of stator) as well as S and S S will repel each other, with the result that the rotor tends to rotate in the anticlockwise direction. Fig. Synchronous motor Stator Slip rings ...
Squirrel cage induction motors. Perhaps the most wellknown type of electric motor in use nowadays is the threephase squirrel cage induction motor. It typically consists of two (2) main components: the stator and the rotor. As their name implies, the stator part is stationary, whereas the rotor part is rotating.
· In such cases, the motor is normally derated or a higher level class insulation material should be used. When it comes time to purchase a replacement motor, be careful to not choose a motor with an incorrect insulation class or you could risk premature failure. To be safe, you should specify a motor with either an equal or higher insulation class.
The wound rotor induction motor has some distinct appliion advantages. Historically, it has been used for hardtostart, high inertia fans, or where power system requirements demand a soft start. With a liquid rheostat, or a static secondary speed control, the wound rotor is an important alternative drive where limited range adjustable speed is required.

Designed, built and tested in the motor factory, solid salient pole rotors are suitable for appliions requiring long duty cycles. This rotor has solid poles and a striponedge field winding. The shaft and pole bodies are of integral construction, produced from a single normalized carbon steel forging.
· Electric motor fluting: What is it and what causes it? Variable frequency drives convert AC input voltage to DC, and then back to pulsewidthmodulated AC voltage with variable frequency. These AC voltage pulses are controlled by insulated gate bipolar transistors (IGBTs). IGBTs have a fast switching time (also referred to as "rise time" or ...
