Permanent magnet DC motor is divided: the rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and aluminum-nickel-cobalt permanent magnet DC motor. Permanent magnet motor includes permanent magnet brushless DC (BLDC) and Permanent magnet synchronous machine (PMSM). The question is whether BLDC can be classified as an AC or a DC motor. There seems to be some confusion within the industry about the terms “permanent magnet synchronous motors” (PMSMs) and “brushless DC (BLDC) motors”. 1) synchronous motor can be divided into: permanent magnet synchronous motor, synchronous reluctance motor and hysteresis synchronous motor. Construction, principle of operation, control and performance of Permanent magnet brushless D.C. AC motor drive system is very important interiorly today,but is very mature abroad. The following figure shows an HIL testing system. 1) DC motor can be divided according to the structure and working principle: the brushless DC motor and a brushed DC motor. Brushless DC motors are also known as Magnet Synchronous motors. SYNCHRONOUS RELUCTANCE MOTORS 9. Construction, principle of operation magnet synchronous motors. Figure 2: Basic block diagram of permanent magnet motor drives. The motor drive simulator includes the DC voltage source, the inverter bridge, and the motor. The evaluation board directly connects with one or two DC brush/brushless servomotors, AC asynchronous motors, AC permanent-magnet synchronous servomotors or stepper motors to form a digital servo-motion control system. Brushless DC motors are synchronous motors suitable for use as a simple means of controlling permanent drives (e.g. ABS pumps, EHPS pumps, fuel pumps or cooling fans).
