The Electric motor

To sustain the development of urban transportation, electrifying private motorized vehicles is a top goal besides the development of public transport. This study aims at investigating the influential factors of continuance intention to use electric motorcycles based on an extension of Expectation Confirmation Theory (ECT).

In low-cost permanent magnet synchronous motor (PMSM) drive systems, the rotor position is usually estimated based on the back-electromotive force. However, such estimation methods have the common drawback of having large errors in low-speed regions. In order to solve that drawback in the startup phase, the I-f startup method is studied as its compatibility with the FOC control structure.

The purpose of the field-oriented control (FOC) is therefore to create a tool that allows the decoupling control of the flux and torque-producing current components from the three-phase AC currents flowing in the coil. The FOC drive system is a system based on the principle of decoupling the above power components thanks to the stator current feedback control (the innermost circuit of the drive system). The FOC-type control method belongs to the class of vector control methods for electrical machines.

This thesis derives closed form equations to describe electromagnetic device characteristics for a toroid, solenoid and a case study induction machine. By considering stored magnetic field energy, this approach allows the relationship between electrical, magnetic and kinetic energy to be quantified and analyzed in ways that allows improved accuracy compared with conventional magnetic circuit modeling methods. This thesis also provides insights into how geometric parameters impact energy transfer and operational characteristics of electromagnetic devices.

The thesis aims to propose some control techniques for mobile target Robot-camera. After that, I studied some of the torque control techniques of joints for the Robot-camera system sticking to the mobile target and the Robot-camera system, paying attention to the motivating motor sticking to the mobile target. Finally, the author also proposed some control algorithms for Robotic-camera arm system with irregular model, external noise and preventing system degradation, using nonlinear sliding controller (TSMC) in combination with Artificial neural networks to estimate uncertain numbers.

MACHINE FEEDBACK DRIVE CONSIDERATIONS Machine Feed Drive Considerations for Resolver Feedback The usual configuration for resolver position feedback is to have the resolver geared to the servo drive motor. Computer-aided design programs for hydraulic drive sizing are based on the fact that the hydraulic resonance is the predominant resonance in the servo loop. With electric drives the mechanical time constant is not of prime consideration since it can be compensated for with the drive compensation....

Concept: Generators convert mechanical energy to electric energy. Motors convert electric energy to mechanical energy. The construction of motors and generators are similar. Every generator can operate as a motor and vice versa. The energy or power balance is : Generator: Mechanical power = electric power + losses Motor: Electric Power = Mechanical Power + losses.

AC motors convert AC electrical energy to Mechanical energy. AC motors: the armature of rotor is a magnet (different to DC motors). the stator is formed by electromagnets (like in DC motors). Effects of AC Supply on Magnetic Poles Consider the rotor to be a permanent magnet. Current flowing through conductors energize the magnets and develop N and S poles. The strength of electromagnets depends on current. First half cycle current flows in one direction. Second half cycle it flows in opposite direction...
