Abstract: A brushless direct current (BLDC) motor has a 3-phase winding 20 and six stator teeth 14, 15 with alternate stator teeth 14 being wound and the remaining stator teeth 15 being left unwound. The winding 20 has three legs, one for each phase and each leg has one coil 22 wound about one of the stator teeth 14. Each leg has a first end A,B,C, arranged to receive electrical power and a second end X,Y,Z, which is connected to the second end of the other legs to form a star connection 24. Selected stator teeth have grooves in a face thereof dividing those teeth into a plurality of stator poles. The motor may be used to drive a fuel pump for an internal combustion engine, typically for a vehicle.
