For applications that Both trapezoidal six-step (BLDC) and sinusoidally commutated motors (permanent magnet AC or PMAC) most commonly have three stator windings arranged in a 3-wire WYE configuration as shown in Fig. DC motors are more expensive to build cuz of the permanent magnets, but it takes way less engineering to get them to work, so in that regard it makes sense why GM used a brushless DC motor to get the autoshow Volt to move 10 feet onto the stage. Brushless motors usable with this product must meet the operational specifications of 50V and 7A maximum, particularly suitable for driving hydraulic pumps in biomedical systems, electrical drives and small lifts, gates, robotics (both industrial and consumer), and industrial automation. The ACIM is an asynchronous machine, meaning that the mechanical rotation is not synchronous with the electrical rotation: there is some slip (a few percent) necessary to induce the rotor current. During start-up, the permanent magnet machine can be used as a brushless DC motor (BLDC), for which there are established means of operating [17]. I am really confused which control system to design for The electronic controllers that drive UQM® machines consist of DC bus capacitance, a three-phase semiconductor bridge (six power switches), and a digital signal processor to control switch timing to optimize system performance. I am really new in game so what i wanted to ask is; is this motor a brushless DC or synchronous permanent magnet motor? For making a 160hp motor for the Volt. Texas Instruments has introduced a new evaluation kit for driving brushless DC and permanent magnet synchronous motors. All production hybred vehicles made by GM currently us a permanent magnet synchronous brushless motor driven by a similar flux vector drive. A DC-source feeds an inverter which in turn is connected to the three phases of the motor.
