Most are already embedded into the motor if it is a brushless DC motor. There are some Hall Effect Sensors that can be bought like the AD22151. This is a Sensor that is offered by the Analog Devices Company and it is one of the newest types of Hall Effect Sensor. The sensor is around $2.45 which is an affordable price but there is also a different Hall Effect Sensor that is sold from Sparkfun, the COM-09312 which is $0.95 and will do the same thing.
