The DC brushless Hall-free motor without feedback is a low cost resolution to DC motor control.

Product Profile:

1.      Product description: the DC brushless Hall-free motor without feedback is a low cost resolution to DC motor control. It is an ideal low-cost resolution to DC speed regulation control systems such as electric cars, electric scooters, refrigerating equipment, ventilating equipment, and automatic equipment.

2.      Standards met:

l        Export products conforming to UL, CE, TUV, VDE and other applicable standards

l        Products conforming to relevant standards of GB4706

3.      Main Technical Parameters :

l        Four voltage input ranges for selection, 12V, 24V, 36V and 48V, with maximum continual current 12A.

l        Driver output power: for driving motors of less than 150W.

l        Speed ratio: 100:1.

l        Speed regulation range 0- rated rotation speed; according to the test result of motors with two pairs of polars, the maximum is up to 6000rpm.

l        Selectable from 600/1200 or 1200/2400 sensor phases.  

l        Speed closed-loop control, with the control mode to be analog voltage speed regulation range of 0-10V, enabling positive or reverse direction and operation.

l        Equipped with under-voltage locking function, as well as cycle-by-cycle current limit features with time delay lock shut-off mode and internal thermal shut-off features.

l        Overall protection function: under-voltage protection; over-voltage protection; current protection; over-temperature protection; fail safe; over-load protection; pumping energy discharge.
