Report KD 683 has been added at the menu KD-reports. The tittle of this report is: “Ideas about a 4-pole, 3-phase permanent magnet generator using the housing of an asynchronous motor frame size 80 and four neodymium magnets size 80 * 20 * 10 mm with a magnet orientation such that the fluctuation of the sticking torque is minimal”. This 4-pole PM-generator makes use of the same principle to flatten the fluctuation of the sticking torque as used for the 8-pole PM-generator as described in report KD 681. An advantage of using the housing of a 4-pole motor is that the standard winding can be used.
