Product Description
Difference between sensorless and sensored brushless motor
Sensored Motors uses the "Hall Effect" to detect the rotor inside the motor and transmit the data to the ESC through a sensor wire. It allows the ESC to control the rotation and the speed of the motors precisely.
Sensorless Motors uses back/counter EMF (Electromotive Force) that detects the rotor position by receiving and interpreting feedback current that was generated by motor as the rotor spins. Basically, it is a contact-less system that is similar to Sensored motors, but uses magnetic field force. In addition, Sensorless motors are more efficient when running at a high RPM than Sensored motors. It would have no friction without the contact and have no heat produced. Unlike Sensored motors that need open space for ventilation, Sensorless motors do not need that so it is usually sealed to prevent dirt or small particles to get in.
In general, sensored motor is smoother compared to a Sensorless motor with the wire connected, and the signals are sent and received correctly. It is noticeable that Sensored motors are smoother especially in the lower end of the motors operations. when the motor is running at low speed, Sensorless motor would occasionally causes cogging, because there isn't enough EMF (Electromotive Force) to send out for the ESC to receive.
Where sensorless brushless motor used?
The 1.2KW 24V 1700RPM Sensorless BLDC Motors are designed for solar pump systems. There are many sensorless brushless motor used in solar pumps systems, which has lower cost compared to sensored brushless motors, and same efficiency.

Advantage of Brushless DC motors
Lower Maintainance and longer lifetime - no brush and commutator erosion
Lower noise - the elimination of brush contact
Higher power to weight ratio
Higher efficiency ( in general higher than 90%)
Lower temperature rise - more efficient heat dissipation due to winding construction
Reduction of EMI
