This paper presents the analysis method of a capacitor-run signal-phase induction motor behavior by using circuit-coupled two-dimensional finite element method. In order to analyze the machines accuracy under rotating magnetic fields, the voltage source, run-capacitor and slide boundary are considered. The voltage coupled model included slip boundary and calculation method is presented, and the simulation...
Starting toque is computed based on two-dimensional (2-D) FEM with a field-circuit coupled analysis. It is discussed that the starting performance of three-phase capacitor motor is better than that of conventional induction motor, in particular, for the operating condition with starting capacitor. The results of calculation are compared to tested values, and it is verified that this new type motor...
Because of the negative-sequence magnetic field, the single-phase induction motor has higher temperature, lower output torque and lower efficiency comparing with three-phase induction motor. Based on negative-sequence magnetic field compensation principle, this paper presents a new type single-phase motor with a special stator windings configuration to weaken the negative sequence magnetic field and...
This paper presents the design and analysis of a new double-stator permanent brushless (DSPMBL) motor for hybrid electric vehicles. The corresponding output power equation is analytically derived. The initial calculation of motor dimensions and parameters, including the core diameter, stack length, permanent magnet size and winding connection modes, are also discussed. A DSPMBL motor is designed....
This paper presents the optimal barrier design in single-phase LSPM (line-start permanent magnet motor) considering the efficiency. The line-start permanent-magnet motor is a synchronous hybrid PM/reluctance motor that is being developed for applications including compressors of air conditioner that require a high-efficiency alternative to the induction motor. To consider nonlinear characteristics,...
The paper mainly researched how the Wye and delta connection affect the copper losses in induction motor under over-voltage condition. The multi-slice time-stepping finite element method (FEM) was utilized to calculate the copper losses of a 5.5-kW skewed motor under no-load and different load conditions respectively. It is shown that, when the motor is supplied with 10% over-voltage, the delta connection...
