Selection Guide

 Ⅰ. Brushless Drive Selection Guide

First, when selecting a DC brushless motor product, the correct voltage should be chosen first. Based on customer requirements, select the rated voltage to determine the drive voltage parameters, fully considering the upper and lower voltage limits during actual use. Ensure the operating voltage does not exceed the specified range of the drive during no-load and full-load conditions. For battery-powered applications, consider the minimum battery voltage and the maximum voltage when fully charged. Our company's drive products cover voltages such as 12VDC, 24VDC, 48VDC, 110VAC, 220VAC, 380VAC, and more.

Second, select the drive current for the motor. The method for choosing brushless drive current is to refer to the motor's rated input current. If actual field current is available, use it as the reference. For loads such as fans and pumps, which have a low overload factor, a current exceeding 30% of the rated current is generally sufficient. For AGV mobile robots, drilling equipment, and milling machine equipment, the current is typically calculated at more than twice the rated current.

Third, select the drive type. Standard drives are two-quadrant drives, while high-performance drives are four-quadrant drives. Two-quadrant controllers can only achieve forward and reverse motion functions but cannot perform forward and reverse braking functions; four-quadrant controllers can achieve both motion and braking functions. When the project application involves downhill control or external forces acting in the same direction as electric steering, two-quadrant drives cannot maintain constant speed and will accelerate. For example, elevators, winches, and hoists may require repeated changes in speed and torque for mechanical operations such as shearing, winding, weaving, and test benches. In applications like yarn winding or conveyor belts for uphill and downhill movement, two-quadrant drives are unsuitable and cannot provide stable speed and torque control. For these applications, a four-quadrant drive control system is recommended.
