Sensorless Bldc Motor Driver Circuit

For proper commutation most 3 phase bldc driver circuits rely either on a sensor based feedback or from an external 3 phase sync signal contrary to this our present sensorless high power bldc motor controller circuit does not depend on sensors or any external signals for operating the motor rather very simply processes the back emfs from the motor winding to produce the required. The figure below shows a typical sensorless bldc motor driver. In the circuit there are 2 pushbuttons one is used to increase bldc motor speed and the 2nd one is used to decrease it.

Sensorless bldc motor driver circuit.

The drv10983 from texas instruments is a three phase sensorless motor driver with integrated power mosfets capable of providing a continuous drive current of up to 2 a. Project circuit schematic is shown below. The sensor less bldc driver circuit simply electrifies the 3 sets of winding in a sequential manner such that the magnetic rotor is able to go through a consistent opposing force enabling the motor to accomplish a sustained torque and rotational force. It is highly integrated and requires few external components.

A minimal application circuit can be achieved with only two external components due to device s high level of integration which includes control algorithm analog circuit and power stage. In order to improve the performance of sensorless brushless dc motor compact the volume reduce the cotsts of production and design our company has devaloped a single chip ic for sensorless burshless dc motor driver which no need connect external counter electromotive force detection circuit. Note that all grounded terminals are connected together. Sensorless bldc motor control with arduino circuit.
