    Multi-sided rotating mirror scanning module motor solution


    With the development of science and technology, applications in the field of optics have gradually become widespread, especially in scientific research and the military. As the scanning component in the optical path, the polygon mirror rotation module is an indispensable part of dynamic measurement equipment such as unmanned driving, laser, robot, and radar scanning. In modern high-precision instruments, the accuracy of optical components is getting higher and higher. The component requirements are also higher. Based on the current high-density microprocessor computing power and brushless motor combination, it can achieve fast response and ultra-high-precision speed control, to achieving more accurate light path control and a wide speed range.

    At present, the multi-mirror mirror rotation modules on the market mostly use mechanical variable speed transmission to output torque. 1>This solution adds additional transmission components, The gap between the machines will increase the output error, also increase the failure rate and cost, which not conducive to digital control. The output speed directly affects the overall life; 2>Usually to extend the service life 

    The output speed is not too high, which limits the scanning frequency and cannot meet the requirements of high-speed scanning.

    Multi-sided rotating mirror scanning module motors

    To solve the problem of multi-face rotating mirror modules on the market, Power Motor adopts MCU+brushless motor+optical encoder design. The brushless motor directly outputs torque to the mirror module, and the high-performance MCU processes floating-point data. Realize high-precision data calculation, with optical encoder and special algorithm processing, the accuracy error of the whole calculation system is controlled within ±0.00001%, coupled with the brushless motor can finally achieve ±0.00005% speed stability output, and leave it to the outside The communication interface (UART/SPI) can monitor internal parameters, speed output and speed setting in real-time (speed range is set at 1000.00-6000.00RPM); and it has the advantages of low noise and long life.

    In the existing control accuracy, design a smaller volume and quality, higher scanning frequency (that is high output speed>=20000RPM), and more convenient for mass production of high-speed multi-face rotating mirror module.

    Power Motor has nearly 20 years of experience in motor customization engineering, especially on scanner motion has accumulated large motor prototype database for customer reference or choice, optional matching controller or encoder, quickly according to customer needs to custom a motor solution meet or exceed customer demand. Power Motor has been a reliable motor provider and manufacturer since 2001.  More information on the  electric scanner motor solution, Please contact our sales engineer.(Skype/Email:info.power@power-motor.com)
