What is PWM control? Explanation of principles and usage examples! Proven results in various fields! Leave application development to Nippo!
Currently, motors are widely used in precision equipment fields such as computers and HDDs. We will introduce the principles and examples of use of the technology called "PWM control," which is used for motor control. PWM is one method of controlling power using semiconductors. It is a type of pulse density modulation (PDM), and a PDM with a constant frequency is called PWM. PWM can be controlled by repeating the ON and OFF of a switch, and this high-speed switching generates a pulse waveform. By changing the duration of the pulses, it controls the power supplied to the load. PWM control has excellent controllability. For example, by controlling the rotation speed of a cooling fan motor, the speed can be adjusted in response to the temperature of the object being cooled, thereby controlling the cooling performance. (Without control, the rotation speed remains constant, which can lead to excessive cooling even at low loads.) Additionally, there is the advantage of increased quietness, as the minimum rotation speed is achieved at low loads, reducing the noise generated by the rotation. Our company applies various technologies and offers application development in a variety of fields. Please feel free to contact us.
