Provide high quality and cheap dc controller motor，What is the role of the BRUShless DC motor controller?
Brushless dc motor controller includes the power conversion circuit, microcontroller (MCU or DSP or other processors) and the signal input output circuit, the controller in the storage program, working controller which can accurately control, dc motor position is detected by sensors, effective control of the motor, such as motor start stop, speed control, direction control and displacement control) motor control for dynamic real-time monitoring, effective protection, resolved to motor for dynamic real-time monitoring, control inaccuracies, protection and reliable technical problems.
The driver mainly includes the drive circuit is the power amplifier circuit, the control signal output from the controller is amplified to drive the motor, and there are generally overcurrent, overvoltage, undervoltage protection circuits in the drive circuit.
Photoelectric encoder is the most widely used dc motor position detection sensor. It is a kind of sensor that converts the mechanical geometric displacement of output shaft into pulse or digital quantity through photoelectric conversion.
Photoelectric encoder is composed of grating disk and photoelectric detection device.Grating plate is in a certain diameter of the circular plate evenly open a number of rectangular holes.Since the photoelectric code plate is coaxial with the motor, when the motor rotates, the grating plate and the motor rotate at the same speed, and the output pulse signals are detected by the detection device composed of light-emitting diode and other electronic components. The current speed of the motor can be reflected by calculating the number of output pulses of the photoelectric encoder per second.In addition, to determine the direction of rotation, the code plate can also provide two pulse signals with phase difference of 90.
