Application
Motors 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.
Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. Because the brushless DC motor is operated in an automatic control mode, it will not add a starting winding to the rotor like a synchronous motor started under frequency conversion speed regulation, and will not produce oscillation and out-of-step when the load changes.
Brushless is that the "brush" in the brush motor is gone, and the role of the brush in the brush motor is to energize the coil in the rotor through the commutator.
Brushless DC motors use electric switches to realize current commutation, and thus continuously rotate the motor. These electric switches are usually connected in an H-bridge structure for a single-phase BLDC motor, and a three-phase bridge structure for a three-phase BLDC motor. Usually the high-side switches are controlled using pulse-width modulation (PWM), which converts a DC voltage into a modulated voltage, which easily and efficiently limits the startup current, control speed and torque. Generally, raising the switching frequency increases PWM losses, though lowering the switching frequency limits the system’s bandwidth and can raise the ripple current pulses to the points where they become destructive or shut down the BLDC motor driver.
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.
