Description

Technical Field

[0001] This utility model relates to the field of motor control equipment technology, specifically to a motor phased start-up energy-saving control device. Background Technology

[0002] A staged motor start-up energy-saving control device is a motor control device that integrates soft start, soft stop, light-load energy saving, and multiple protection functions; it is commonly referred to as a soft starter. Its main functions include achieving a smooth, shock-free motor start-up process and adjusting parameters during the start-up process, such as current limiting and start-up time, according to the characteristics of the motor load. As motor design and operating characteristics indicate, in ordinary motor control mode, the motor is most efficient when running at full load. During relatively light-load operation, the motor generates significant ineffective energy loss because the input voltage and frequency are much higher than the actual required values. Similarly, in inverter control mode, the motor's input voltage and frequency are relatively higher than the actual required values, resulting in corresponding ineffective energy loss.

[0003] For example, CN201620042023.3 discloses "An Energy-Saving Motor Control Device", which uses an adaptive vector control method based on the load to adjust the input power of the motor in real time, so that the motor receives the voltage most suitable for its immediate load, thereby ensuring that the motor always operates in the best energy-saving state, thus effectively saving precious electrical energy.

[0004] However, existing motor tiered control devices mostly use built-in heat dissipation holes for heat dissipation during use. However, the heat dissipation effect of the heat dissipation holes is relatively average, which can easily cause deformation of the internal circuit board, making the circuit prone to short circuits and causing the motor controller to malfunction.
