This paper presents the development of an experimental platform to test a real-time controller for a small Permanent Magnetic Brushless Direct Current (PM BLDC) motor using a Controller Area Network (CAN) communication bus. The CAN communication bus transmits and receives information between modules to control the speed, acceleration/deceleration, and rotational direction of the motor. The desi...

(May 2008) Salih Baris Ozturk, B.S., Istanbul Technical University, Istanbul, Turkey; M.S., Texas A&M University, College Station Chair of Advisory Committee: Dr. Hamid A. Toliyat This work presents the direct torque control (DTC) techniques, implemented in fourand six-switch inverter, for brushless dc (B...

In this paper, one-cycle control (OCC), as a constant-frequency PWM control strategy for current control of a six-switch brushless dc (BLDC) motor drive is investigated. Developed current regulator is a unified controller and PWM modulator. Employing the one-cycle control strategy, decreases the torque ripple resulted from the conventional hysteresis current controllers and therefore, the vibra...

A bearingless brushless direct current (BLDC) motor incorporates the function of magnetic bearings into a BLDC motor, making it new type high-performance motor. In this paper, main windings are used to generate radial force cancellation by injecting required dc current, “integrated winding configuration”.

This paper aims to develop the 42V BLDC fan motor for hybrid electric vehicle using metal powdered core. So, the influence on a motor design by metal powder is described and the powder is applied as a direct replacement of lamination core. This point is focused upon a comparison of brushless dc motors, built with a powdered stator and Si laminated stator, which also has been redesigned to take ...

This paper presents the speed regulation scheme of a small brushless dc motor (BLDC motor) with trapezoidal back-emf consideration. The proposed control strategy uses the proportional controller in which the proportional gain, kp, is appropriately adjusted by using genetic algorithms. As a result, the proportional control can perform well in order to compensate the BLDC motor with load disturba...
