PROBLEM TO BE SOLVED: To increase drive output by increasing a ratio of rotor teeth contributing to torque generation in operation.SOLUTION: A switching motor is a so-called 6S8 P type which has a 3 phase armature winding 2 mounted on a stator core 5 and 8 rotor teeth 11 installed on a rotor core 1, where the 3 phase armature winding 2, field magnetic winding 3 for generating a magnetic field, and permanent magnet 4 for reinforcing the magnetic field are installed only on the stator core 5. The armature winding 2 is arranged "in an armature slot 6 skipping two field magnetic slots 7", and the field magnetic winding 3 is arranged "in two field magnetic slots 7 sandwiched by two armature slots 6". Thereby, a ratio of stator teeth 8 magnetically attracting the rotor teeth 11 can be increased; or a ratio of the rotor teeth 11 contributing to torque generation can be increased from 4 of a conventional technology to 6 to enhance output torque. |
