This paper provides a technical review of position and speed sensorless methods for controlling Brushless Direct Current BLDC motor drives, including the background analysis using sensors, limitations and advances. The performance and reliability of BLDC motor drivers have been improved because the conventional control and sensing techniques have been improved through sensorless technology. Then, in this paper sensorless advances are reviewed and recent developments in this area are introduced with their inherent advantages and drawbacks, including the analysis of practical implementation issues and applications. For the past two decades several Asian countries such as Japan, which have been under pressure from high energy prices, have implemented variable speed PM motor drives for energy saving applications such as air conditioners and refrigerators [ 1 ]. On the other hand, the U.
In the period of the 18 th century itself, there was the evolution of DC motors. The development of DC motors has widely enhanced and they are significantly applied in multiple industries. In the early period of the s and with the enhancements made in the year , DC motors were initially developed by the British researcher Sturgeon. He invented the initial commutator type of DC motor where it has the capability to simulate machinery too. But one might wonder what the functionality of the DC motor is and why it is important to know about DC motor speed control.

The frequency of variation is proportional to the motor speed and the rotor position can also be detected by monitoring the changes for each collector blade. The performance of the motor torque speed characteristic using this system as its feedback has been evaluated through laboratory testing.
In practice, the variation of these three factors is used for speed control. Thus, there are three general methods of speed control of D. Figure: a Speed control of a d. Shunt motor by armature resistance control. Series motor by armature resistance control.
A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy.Reply
