It is the outer part of thethree phase induction motor. Its main function is to support the stator core and the field winding. It acts as a covering, and it provides protection and mechanical strength to all the inner parts of the induction motor. The frame is either made up of die-cas...
1. A connecting device for the beginnings and ends of windings of groups of the coils in the induction motor rotor winding of an electric motor, in which there is arranged in common grooves of a stack of stator laminations the stator winding of a two-pole universal motor, and that of an...
Moreover, the operation regions of an induction motor available by speed control are examined. Second, the equivalent circuit and the output torque characteristic for two rotor construction types of cylindrical and salient pole are discussed... SH Kim - 《Electric Motor Control》 被引量: 0发表:...
Definition:A slip ring induction motor is referred to as an asynchronous motor as the speed at which it operates is not equal to the synchronous speed of a rotor. The rotor of this type of motor is wound type. It comprises of a cylindrical laminated steel core and a semi-closed groove a...
Advantages of Synchronous Motor It can be operated at any desired power factor (unity, leading, or lagging) by changing excitation. It can be used for power factor correction. It can be constructed with air gaps that are wider than that in induction motors. This makes it more stable mechanic...
(Krumhansl,2002). On the other hand, culture-specific cues are clarified as both the living environments and subjective interpretation of the environments (Geertz,1973). The BRECVEMA (Brain stem reflex, Rhythmic entertainment, Evaluative conditioning, Contagion, Visual imagery, Episodic memory and ...
same as that of aninduction motor, but a permanent magnet is used as a rotor to create a magnetic field. Hence there is no need to wound field winding onthe rotor. It is also known as a 3-phase brushless permanent sine wave motor. Thepermanent magnet synchronous motor diagramis shown ...
aThe objective of this report is to provide a technical source of information concerning ‘pz’ type machines based on the construction of our GASCO YWKK710-4 5010kW induction motor. The costumer requirement was to have an Ex ‘p’ machine according to the hazardous area where it will be in...
As compared to induction motor drives, the control algorithm based on the field is simple The exact torque can be suitable that doesn’t affect the temperature of the rotor. The rotor of this motor is low cost as compared to other motors like induction and permanent magnet. ...
Tests are conducted in three different operating conditions, named C1, C2, and C3, defined by distinct braking torque values and the motor speed (Table 3). The braking force values have been set to 0.1 and 0.2 Nm because of the low power of the electric motor. Indeed, higher values ...
