Two models of the three phase induction motor stators
between different stator
slot size used in this investigation.
The ANSYS finite element analysis software was used to simulate temperature effect on the clearance between the stator
Consequently, excitation rotor field coil directly from stator
coil is suggested.
steel losses are caused by the hysteresis and eddy-currents in the stator
core [7, 9],
The idea behind vector control is that the stator
current of the induction motor is decomposed into orthogonal components as a magnetization component (flux producing) and a torque component.
Motors may have three input power taps for low, medium and high speed, each tap is wired internally to aggregate the stator
windings into a specific number of poles, so that the different taps cause the motor to operate with a different number of poles and thus at a different speed.
The intent of this paper is to investigate the impact of SAGE forms, including rotor offset, stator
concave deformation, stator
convex deformation, stator
ellipse deformation, and mixed SAGE composed of rotor offset and stator
deformation, on the rotor UMP characteristics.
Theoretical analysis of direct torque refers to the coordinate transformation of coordinate system diagram, just like what illustrated in Figure 2, among which A, B, C is three phase stator
static coordinate system; [alpha], [beta] is two phase static stator
coordinate system, [alpha] axis is defined on the A axis relative to the stator
winding; x, y is two phase stator
By simply enlarging the stator
length, the cost of conductors and steel lamination is increased.
rdq] represent respectively the rotor voltage' s positive and negative sequence components in SRF; [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] represent respectively the stator
current's positive and negative sequence components in SRF; [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] represent respectively the rotor current's positive and negative sequence components in SRF; [[PSI].
Complex geometry, non-linear behavior of core materials and actual representation of winding distribution on the stator
slots can be efficiently modeled using FEM.
The gantry collapsed while turning, dropping the stator
onto the turbine floor and, along with death and injury, also caused significant damage to the building and its systems.
Topologies for double-sided AFPM machines are axial-flux one-stator
-two-rotor (this structure is a type of TORUS) and two-stator
-one-rotor, which is known as axial-flux interior rotor (AFIR) , while either of the two arrangements (external stator
or external rotor) is practical.
The range now includes high and low resolution versions (14 to 21 bit options); IP67 integral cable; servo clamp format with plain rotor; a 55[degrees]C operating temperature option; and mix-and-match rotor and stator
A new rotary actuator (also called a rotary solenoid) promises to boost speed, precision and response while slashing costs by one third, thanks to a new stator
