Problems solved by technology
[0004] But the above-mentioned existing motor system has the following deficiencies: 1. The operation mode of the motor is single; 2. The motor driver only controls the motor body by changing the frequency and duty cycle of the drive signal, and does not control the shape of the drive signal. , continuity and the number of driving phases of the motor body; 3. When the motor body is driven by a DC signal, it only passively regenerates the reverse electromotive force generated during commutation, and will not actively respond to the operation mode and (or ) running state to control the commutation time, so that the motor body can run with higher efficiency
4. Due to the above reasons, the efficiency of existing energy regeneration circuits is not high

The invention discloses a hybrid motor. The rotor of the hybrid motor can be composed of permanent magnet poles and an induction magnet pole pair; a motor body runs in a manner of a synchronous motor when a magnetic field generated by a stator coil in the motor body is used for driving the permanent magnet pole pair in the rotor, and the motor body runs in a manner of an induction motor when the magnetic field is used for driving the induction magnet pole pair in the rotor; a controller (B3) changes the conduction sequence and / or quantity of switch elements in a half-bridge drive circuit, forming a full-bridge drive circuit, in a motor driver (B4) according to the operation mode and / or operation state of the motor body, outputs direct current or sine drive signals which are continuous or discrete in amplitude, and changes the drive phase number of the motor body. An energy regeneration circuit composed of a function selection switch or the extra full-bridge rectifier circuit, and the hybrid motor of the motor driver achieving the functions and the motor body are applicable to a motor which comprises permanent magnet poles and can convert electric energy into mechanical energy in an electromagnetic induction manner.
Description
technical field [0001] The present invention relates to the driving technology of synchronous and induction motors, more specifically, relates to a motor driver capable of outputting continuous or discrete driving signals with different phase numbers, phases and shapes in amplitude, and by selecting single-phase or several-phase independent A function selection switch for the stator coil function or an energy regeneration circuit composed of a function selection switch and a full-bridge rectifier circuit at the same time. Background technique [0002] Motors are widely used in various fields, such as machinery, petrochemical, electric power, etc. Motors are generally composed of stators, rotors and casings, and can be divided into DC motors, synchronous motors and asynchronous motors according to their structure and working principle. In recent years, with the rapid development of the industrial field, the performance requirements of the motor are getting higher and higher, ...
