As recently as two years ago, brushless motors were significantly more expensive than brush motors. However, advances in design and materials have triggered dramatic price drops in brushless motors.

Texas Instruments has introduced 70W brushless dc motor drivers with code-free sensor-less ield-oriented or trapezoidal control. In common, the devices include a set of commutation control algorithms ...
