“…The electronic circuit for commuting a BLDC motor consists of a 3-phase inverter, rotor position detector, and motion controller. The motion controller can be implemented in a microcontroller [14]- [17], digital signal processor (DSP) [18], or field-programmable gate array (FPGA) [13], [19]. The rotor position can be calculated using the information from the Hall sensors [14], [18]- [20] or electromotive force (back-EMF) [15], [16], [21]- [23].…”

<p>This research is focused on the design and implementation of an electronic circuit for commuting a brushless direct current (BLDC) motor and its data acquisition system, as well as conducting experiments on them. We propose a drive circuit using two modules, each consist of a dual H-bridge, that are cheap and can be easily obtained. Two different commutation methods, namely six-step and sine-wave commutations, are applied. Each of these implements a different way for its open-loop speed control, i.e., a voltage-controlled-current-source is implemented along with the six-step commutation and the step duration approach is implemented along with the sine-wave commutation. The experiment data are acquired using a developed desktop application. Some experiment results lead us to find that, on its own, both commutation methods have a narrow range of speed. Nevertheless, if both methods are used together, this range can be increased. Also, the relation between speed and its controlling signals for both methods are shown.</p>
