Problems solved by technology

[0004] The fan water pump driven by the EC fan needs the automatic control system to carry out remote control according to the controlled parameters. At the same time, in order to ensure the safety of the operation, the site should have the manual / automatic switching management function. At present, it is mainly realized by the strong current secondary circuit and the digital display instrument. Inflexible, high installation labor, heavy maintenance workload

Embodiment 1

[0017] Example 1: See figure 1 , an EC motor adjustment control module, including a CPU, an indicator light, a data display module, a control panel, an EC motor and a sensor module, wherein the sensor module collects the running state data of the EC motor and transmits it to the CPU, and the CPU also The indicator light, data display module and control panel are respectively connected, and the CPU controls the operation of the EC motor according to the input parameters. The EC motor control panel is manually set to the CPU for manual / automatic mode and EC fan speed setting signal; the CPU controls the power supply and power failure of the EC motor; the CPU sends an analog control signal to control the speed of the EC motor; the EC motor feeds back the analog The signal is sent to the speed data of the CPU; the CPU sends the power status and communication status of the EC motor control panel; the CPU sends the EC motor control panel to digitally display the current valve openin...

Embodiment 2

[0018] Embodiment 2: On the basis of Embodiment 1, there is a communication unit inside the CPU, which can complete the communication with the upper computer and facilitate the transmission of information.

Abstract

The invention discloses an adjustment control module of an EC motor. The adjustment control module comprises a CPU, an indication lamp, a data display module, a control panel, the EC motor and a sensor module and is characterized in that the sensor module is used for acquiring running state data of the EC motor and transmitting the running state data to the CPU, the CPU is further connected with the indication lamp, the data display module and the control panel, and the CPU is used for controlling running of the EC motor according to an input parameter. By the adjustment control module of theEC motor, manual / automatic key switching can be performed, and functions of switch control, adjustment control and state monitoring on a draught fan and a water pump which are driven by the EC motor can be achieved by two modes of manual operation and automatic operation.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an EC motor regulation control module. Background technique [0002] Brushless DC motors use semiconductor switching devices to achieve electronic commutation, that is, electronic switching devices are used to replace traditional contact commutators and brushes. It has the advantages of high reliability, no commutation sparks, and low mechanical noise. It is more and more widely used in the drive and control of fans and water pumps, showing obvious energy-saving effects. [0003] The EC motor is a DC brushless motor, which can be adjusted by analog signals, such as 0-10V, 4-20mA. [0004] The fan water pump driven by the EC fan needs the automatic control system to carry out remote control according to the controlled parameters. At the same time, in order to ensure the safety of the operation, the site should have the manual / automatic switching management function. At present, it...
