Application
A Brushless DC Motor accomplishes commutation electronically using rotor position feedback to determine when to switch the current. Feedback usually entails an attached Hall sensor or a rotary encoder. The stator windings work in conjunction with permanent magnets on the rotor to generate a nearly uniform flux density in the air gap. This permits the stator coils to be driven by a constant DC voltage (hence the name brushless DC), which simply switches from one stator coil to the next to generate an AC voltage waveform with a trapezoidal shape.
The Brushless DC Motor is configured like a DC motor turned inside out with the permanent magnets on the rotor and the windings are on the stator. Because of the absence of brushes the disadvantages are eliminated such as sparking, noise, efficiency, and also enable very high speed compared to universal motors. These motors are also known as electronically commutated motors (ECMs or EC motors) and are synchronous motors that are powered by a DC electric source through an integrated inverter, which produces an AC electric signal to drive the motor; additional sensors and electronics control the inverter output.
Motor Advantages
- Higher efficiency and reliability
- Lower acoustic noise
- Smaller and lighter
- Greater dynamic response
- Better speed versus torque characteristics
- Higher speed range
- Longer life
Brushless DC Motor is easily controlled with position feedback sensors and generally performs well, especially in speed/torque. With these advantages, BLDC motor will spread to more applications. Moreover, with the development of sensorless technology, BLDC motor will become convenient or indispensable in applications with environmental limitations.
Construction of BLDC Motors
Brushless DC Motor can be constructed in several different physical configurations. In the conventional (also known as inrunner) configuration, the permanent magnets are part of the radially center core. In the outrunner (or external-rotor) configuration, the radial-relationship between the coils and magnets is reversed.
The stator coils in the outrunner configuration form the center core of the motor, while the permanent magnets spin within an overhanging rotor which surrounds the core. For this application, the inrunner configuration was selected. The rotor is in the center with the permanent magnets and that the stator contains the windings.
