 179W 57mm Brushless DC Electric Motor Bldc Motor For Solar Power System 0


The brushless DC motor is composed of a motor body and a driver, and is a typical mechatronic product. Brushless motor refers to the motor without brush and commutator (or slip ring), also known as commutator-less motor.
Parameters to be refered when Select a brushless dc motor:
Maximum torque: It can be obtained by adding the load torque, moment of inertia and friction. In addition, there are some additional factors that affect the maximum torque, such as the resistance of the air gap.
Square modulus torque: It can be roughly regarded as the continuous output torque required by the actual application, which is determined by many factors: maximum torque, load torque, moment of inertia, acceleration, deceleration, and running time.
Speed: This is the speed with application requirements. The speed demand of the motor can be determined according to the speed trapezoidal curve of the motor. Usually, a margin of 10% should be left in the calculation.
