Conventionally, BLDC motors are commutated in six-step pattern with commutation controlled by position sensors. To reduce cost and complexity of the drive system, sensorless drive is preferred. The existing sensorless control scheme with the conventional back EMF sensing based on motor neutral voltage for BLDC has certain drawbacks, which limit its applications. This paper presents the dynamic ...

Aim of this work is the design and realization of a driving system for monitoring and controlling of a BLDC motor with Hall sensors embedded. The realized system is composed by three principal blocks: the control electronic board, the power driving board and the BLDC motor. The first block is based on the STM32 Nucleo development board assembled with the second one, the ST-X-Nucleo-IHM07M1 moto...

Permanent Magnet Brushless DC motors are used wide applications in industries due to their high power density and easy to control. These motors are generally controlled using a three phase power semiconductor bridge. For starting and to provide proper commutation sequence to turn on the power devices in the inverter bridge the rotor position sensors are required. Based on the rotor position, th...

BLDC motors are the workhorses in most light industrial applications. In some cases, Halleffect position sensors are used to simplify control logics for controlling these motors. BLDC motors, by the nature of currents through them, are somewhat noisy and a little less efficient. These disadvantages plus the cost of sensors are an integral part of these drive systems. However, if the motor can b...

Received Feb 14, 2017 Revised Apr 14, 2017 Accepted Apr 29, 2017 Brushless DC (BLDC) motors are becoming an increasingly popular motor of choice for its unique characteristics. The BLDC motor drive is assumed to have trapezoidal back-electromotive force (EMF), rectangular phase currents and together produces the desired torque. However, practical back-EMF waveform might not be exactly trapezoid...

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...
