This work presents a simple method for obtaining the main parameters, such as the torque constant and the d - and q-axis inductances $L_{d}$ and $L_{q}$, for a brushless internal permanent magnet motor by measuring the machine torque during testing. These tests are relatively simple to carry out compared with other test procedures described in the literature, and they neither require sophisticated...
This paper presents a method for obtaining the main parameters, such as the torque constant and the d- and q-axis inductances Ld and Lq, for a brushless internal permanent magnet motor by measuring the machine torque during testing. These tests are relatively simple to carry out compared to other test procedures described in the literature and do not require sophisticated equipment. The machine under...
While permanent magnet motors are increasingly being utilized in high performance and high power-dense drives, the induction motor is still almost universal for new electric train drives and gaining popularity in vehicular drives. This is on top of their traditional role as an industrial drive motor for pumps and fans and also their use in servos. The key to good control of these motors is accurate...
