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.
DC motor is an electrical device that converts direct current energy into mechanical motion. There are a variety of motors available for different applications and power requirements, from tiny devices for medical devices - just a few millimeters in diameter - to custom designs that produce thousands of horsepower.
The two most common types of DC motors are called brushled DC motors and brushless DC motors (BLDC). Although the underlying physical principles are the same, the structure, performance characteristics and control methods are quite different.
When the DC power supply is connected to the brush, the armature coil is energized, turning it into an electromagnet and causing it to rotate so that its north and south poles are aligned with the north and south poles of the stator, respectively. When the commutator rotates, the motion causes the polarity of the current flowing into the armature coil - and the direction of its magnetic field - to reverse. The armature rotates toward the new alignment point, the current reverses again, and the armature continues to rotate.
This way of reversing the current is called mechanical commutation - the mechanical rotation of the shaft provides the feedback needed to switch the polarity of the current.
Brush DC Motor Control
In mechanical commutation, the control of brushed DC motors is conceptually simple. Constant speed motors only need DC voltage and switches; Changing the voltage can change the speed over a wide range.
For speed control, pulse width modulation (PWM) signals can be used to generate an average voltage. The motor winding acts as a low-pass filter, so the high frequency PWM waveform will produce a steady current in the motor winding. For more accurate speed regulation, speed sensors such as Hall effect sensors or optical encoders can be added to form a closed-loop control system.
