This paper presents a new and original Mono inverter Multi parallel Permanent Magnet Synchronous Motor (PMSM) system. To obtain the stability of such a system, each of the motor synchronisms should always be respected regardless of their load torque. In this case, only one motor, called "master motor", will be self-piloted. If the chosen master motor is the one with the highest applied load torque, synchronism is respected for each of the motors. To find this machine, a solution which compares the rotor positions is thus developed. Experimental results are given for a system with 2 PMSM plugged in parallel. The proposed solution can however be applied to systems whatever the motor numbers, therefore additional simulations are provided for a 4 PMSM system.
