Embodiment Construction

[0019] The present invention will be described in detail below with reference to the drawings and embodiments.

[0020] An embodiment of the present invention provides a motor drive device integrating multiple outputs. The device includes: a drive control unit configured with M motor ports and N drive circuits; N motors, each of which The motor ports are respectively connected to one of the motors. In another preferred embodiment of the present invention, one motor port can be connected to P motors. In other words, the number of motor ports and the number of motors can be in a one-to-one correspondence, and the numbers can also be unequal. One motor port can also provide power to multiple motors. The drive control unit sends corresponding drive signals to the drive circuits corresponding to the motors according to the working conditions of the motors, and the drive circuit controls the motor ports to differentiate and allocate corresponding drive power supplies to the motors, wh...

Abstract

The invention provides an integrated multi-output motor driving device which comprises the components of a driving control unit which is provided with M motor ports and N driving circuits; and N motors, wherein each motor port is connected with one motor or one motor port is connected with P motors. The driving control unit transmits a corresponding driving signal to the driving circuit which corresponds with each motor according to the working condition of each motor, and the driving circuit makes the motor port distribute corresponding driving to the motor for supplying electric power, wherein N>=P>=M>=1 or N>=M>=P>=1. Finally the motor driving device realizes driving control on a plurality of motors by one driving control unit, thereby sufficiently exerting the use value of the drivingcontrol unit, reducing purchasing cost of a user and realizing resource efficiency maximization.

Description

Technical field [0001] The invention belongs to the field of motor control, and specifically relates to an integrated multi-output motor drive device and control method. Background technique [0002] At present, in the field of motor control systems, the usual structure is to control the operation of the motor through a dedicated drive control unit. Take the battery-powered electric vehicle as an example. Its energy is derived from the power battery. The battery distributes and transmits electric energy to the motor through the motor drive control unit; when the motor performs work according to the program set by the drive control unit, it converts the electrical energy into Mechanical energy to achieve their respective functional purposes. Its advantages are simple structure, low operating cost, convenient maintenance and zero emission. Including but not limited to the motor control systems in electric vehicles, there are the following shortcomings: 1. One motor needs to be eq...
