Also, the torque ripple that is the cause of noise was able to reduce it, by adopting a sine wave drive PWM inverter system. We describe the outline of the DD motor and inverter system that applied to this washing machine in this paper. 展开 ...
motor-side converter of a traction drive system. When a train starts, it acts as an inverter, and when the train brakes, it acts as a rectifier. Therefore, a traction inverter can also realize rapid and smooth conversion between traction and brake. Its parameters are presented inTable 4.21....
In this chapter we tell about the history of drive systems, the types of drive systems, electronic drive technology, useful mechanical formulae, moment and torque of a motor and finally the run down test to determine the moment of inertia of a drive system. We start with a theoretical speed...

A fault tolerant inverter with minimum-switch based permanent magnet synchronous motor(PMSM) direct torque control(DTC) drive system was investigated.The fault tolerant inverter,which was used to replace the standard 6-switch 3-phase inverter in the normal PMSM DTC drive system,can be reconfigured ...
Comparative Analysis of Speed Control Methods for PMSM Drive Fed Electrical Vehicle In this paper, field-oriented control (FOC), direct torque control (DTC) and space vector modulation-DTC (SVM-DTC) of multi-level inverter (MLI) fed perman... SK Kakodia,AK Panda,G Dyanamina 被引量: 0发表...
For most fans, the belt drive between the motor and the fan can be changed to obtain the correct fan speed; most pumps are direct drive, so the motor size, slip, and efficiency must all be carefully considered to make the best selection. Sign in to download full-size image Figure 4. ...
Abatteryelectric vehicle (BEV) is a type of EV that uses the energy from the battery to drive the electric motor and no other source of energy is used like anICEorhydrogen fuelcell. The technologies that are involved in BEVs are electric motors,motor controllers, and the battery pack. The...
