Abstract
A brushless direct current electric machine, comprising a stator with a hub and first stator pole teeth, which extend radially outward from this hub and have excitation coils, and with second stator pole teeth, which do not have excitation coils, interposed the first stator pole teeth, and has a rotor equipped with permanent magnets, which can rotate around the stator. The electric machine also has a base plate in which a rotor shaft bearing is inserted directly into the hub of the stator which fastens each of the second stator teeth to the base plate. The base plate is made of sheet metal and has supporting nipples oriented toward the second stator pole teeth. The second stator pole teeth have holes through which screws extend, which are screwed into the supporting nipples. The electric machine operates as a brushless direct current motor and is manufactured inexpensively.
