The cores are evenly spaced from each other in the circumferential direction. A space is formed between neighboring cores. Each space receives one magnet. The magnets are magnetized circumferentially such that side surfaces of the magnets have corresponding polarities. The housing is made of magnetically permeable material, surrounding and covering radially outer ends of the magnets and cores.
