HOLRY offer a NEMA 17 customized brushless DC motor (BLDC Motor) and matching amplifiers for motion applications requiring higher speeds. The outstanding advantages of brushless DC motor is the convenience of speed regulation, higher power density and over load capacity.
DC motor brushless eliminates the carbon brush and slip ring structure, so it can run at low speed and high power. In addition, it is much smaller in weight and volume than brushed DC motors, the corresponding moment of inertia can be reduced by 40% to 50%. The motor has soft start soft stop, good braking characteristics, so it will save the original mechanical brake or electromagnetic brake device. The motor itself has no excitation loss and carbon brush loss, eliminating multi-stage deceleration, the overall power saving rate can reach 20% ~ 60%.
The speed control of dc motor brushless is essential for making the motor work at desired rate. The speed can be controlled by controlling the input dc voltage. When the motor works in normal mode or runs below rated speed, input voltage of armature is changed through PWM model. When the motor is operated above rated speed, the flux is weakened by means of advancing the exiting current.
