General control module for permanent magnet motor

Abstract

The invention discloses a general control module for a permanent magnet motor. The general control module comprises an auxiliary power supply module, the permanent magnet motor and an upper computer. The output end of the auxiliary power supply module is electrically connected with a control module, and a rotary transformer, a cooling fan and a Hall sensor are mounted on a permanent magnet motor of the auxiliary power supply module; and the control module comprises a CPU controller and an FPGA controller connected with the CPU controller. The general control module has various control functions, can be compatible with control of a brushless direct current motor and a permanent magnet synchronous motor, control with a position sensor and control without a position sensor, realizes control logic of the brushless direct current motor and the permanent magnet synchronous motor, and is beneficial to popularization and application of the universal motor control module.
