Abstract

The invention discloses an ECM motor compatible with multiple universal interfaces, a heating, ventilation and air conditioning HVAC system and a signal conversion method. The ECM motor comprises a motor body and a motor controller. Motor controller comprises a control circuit board, the control circuit board comprises a power supply part, a microprocessor, an IGBT inverter circuit and a pluralityof universal interface modules. The various universal interface modules refer to at least two of a multi-pin communication interface module, a multi-wire communication interface module, a multi-gearcontrol interface module or a PWM signal communication interface module. According to the interface signal condition of the connected heating ventilation air conditioner HVAC system, one universal interface module can be selected from the multiple universal interface modules so as to establish a communication mode connection between the microprocessor and the heating ventilation air conditioner HVAC system. Connection between a heating ventilation air conditioner HVAC system control main board and a motor can be well coordinated; compatibility is improved; and great convenience is brought to maintenance of the after-sales market.

Description

Technical field: [0001] The invention relates to an ECM motor compatible with multiple common interfaces, in particular to an ECM motor compatible with multiple communication modes and a HVAC system with a common interface and a signal conversion method thereof. Background technique: [0002] In recent years, in the field of HVAC, different brands of HVAC use different control boards, and different control boards use corresponding types of motors. During after-sales maintenance of existing products, if the maintenance needs to replace the motor or the main control board, it may The main control board of the product is not compatible with the motor, which brings a lot of inconvenience to after-sales maintenance. [0003] The main reason for the poor compatibility between the main control board and the motor is that the main control board and the motor have a one-to-one corresponding control method. After-sales maintenance of the product is usually to find the corresponding mo...
