Embodiment Construction

[0045] The specific implementation of the motor driving device and the driving method in the present invention will be described below with reference to the accompanying drawings. Such as figure 1 The schematic diagram of the principle of the motor drive device is shown. The motor drive device detects the models of different DDM motors, and matches the detected model with the driving parameters of the DDM motor stored in the motor drive device, and drives the DDM motor to run.

[0046] The motor drive device includes an interface unit 10 , a main control unit 11 and a storage unit 12 connected in sequence.

[0047] The interface unit 10 is used for detecting code information of motors of different models. Such as figure 2 What is shown is the first embodiment of the present invention. In this embodiment, the function of the interface unit 10 can be realized by a voltage divider circuit. The voltage dividing circuit includes a resistor R2 and a capacitor C3, wherein one end...

Abstract

The invention provides a motor driving device, which comprises an interface unit, a storage unit and a main control unit, wherein the interface unit is used for obtaining code information of the connected motors, the storage unit is used for storing the code information of each motor and the corresponding driving parameter of each motor, the main control unit is respectively connected with the interface unit and the storage unit, and the main control unit is used for calling the motor driving parameter corresponding to the code information from the storage unit according to the obtained code information, so as to drive the motor to run. The invention also discloses a motor driving method. The motor driving device has the advantage that the motor model can be automatically identified by a simple identification circuit, and then the motor is driven, so as to realize the self-adaptive performance of the motor.

Description

technical field [0001] The invention relates to a motor drive device and a drive method. Background technique [0002] After the establishment of a new round of home appliance energy-saving projects, washing machines were included for the first time. This has undoubtedly accelerated the pace of technological innovation of energy-saving washing machine motors. At present, many washing machine motor companies are stepping up the development of new energy-saving and noise-reducing motors. Most washing machine motors use DC motors with deceleration clutch drive (DDM). [0003] Since the DDM DC motor itself has a strong dependence on the product design capability, production automation level, and quality control methods of the manufacturer, the current DDM DC motor market is faced with many manufacturers, complex types of motors, and differences in motor characteristics. In order to To make each type of DDM motor achieve the best performance matching in its complete machine pr...
