Abstract
To lessen mounting time and to optimize positioning of the Hall generator, the Hall generator and control electronics influenced by the generator so as to actuate a brushless dc motor are arranged on a common substrate and are provided with a common protective envelope whose dimensions are somewhat narrower than the cross-section of the motor slot. This substrate is inserted in the motor slot so that the Hall generator is located outside the slot and in the effective magnetic field of the motor's permanent magnet.
