Vibration analysis of a permanent magnet synchronous motor by a pole/slot combination
نویسندگان
چکیده
A sixteen-pole eighteen-slot (16p/18s) permanent magnet synchronous motor (PMSM) developed in Korea Electrotechnology Research Institute (KERI) for a vertical articulated robot is chosen as reference model, and other two pole/slot combinations (20p/18s, 20p/24s) are together compared terms of electrical mechanical performance. Radial force density varying time space decomposed through Fast Fourier Transform (FFT), vibration calculated from the harmonics radial force. The 20p/24s best due to its mode 4 among three combinations. Additionally, variation with respect torque between 16p/18s 20p/18s. Despite same number slots both motors, slope 20p/18s greater than that different poles. As result, worse 16p/18s.

متن کاملOptimum design of a double-sided permanent magnet linear synchronous motor to minimize the detent force
In the permanent magnet linear synchronous motor (PMLSM), force ripple is harmful, useless and disturbing. The force ripple is basically composed of two components: detent force and mutual force ripple. This force is influenced by the geometric parameters of the permanent magnet (PM) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stato...
