The advantages of closed loop stepper motor are low cost, high-performance feedback system and advanced DSP to close the loop of the step motion control system. Such control can improve the performance of the closed-loop stepper motor driver, making it superior to open-loop systems.
Because brushless DC motor can develop high torque with good speed response, they may be used for applications that require variable speeds, such as pumps and fans. The motors achieve a variable speed response by operating in an electromechanical system with a rotor position feedback sensor and electronic motor controller. Thanks to their lower cost and versatility, brushless DC motors are often used as extruder drives. They function by turning a screw that compresses polymer materials. While the action might seem simple the motor offers precision to avoid variations in the part density, which ensures accuracy. Incidentally, the motor offers high torque over its speed range with little to no short-term positional errors.
In addition to not having brushes, low voltage brushless DC motor lacks a mechanical commutator. The reduction in the number of components means there are fewer parts that wear out, break, need replacing, or require maintenance. Brushless DC motor manufacturers design the motors to be more efficient, reliable and durable. Some custom BLDC motors even have a lifespan of 30,000 hours or more. Because the motors’ internal components are enclosed, they operate with less noise and electromagnetic interference. The enclosed design also makes the motors suitable for environments with grease, oil, dirt, dust and other debris.
In regard to industrial applications, high voltage brushless DC motor is often used in variable speed, servo, actuation and positioning applications where stable operations and precise motion control are vital. Common uses of brushless DC motors in industrial engineering are linear motors, servomotors, actuators for industrial robots, extruder drive motors and feed drives for CNC machine tools. Industrial robot Linear motors produce linear motions without transmission systems, making them more responsive and accurate. Servomotors are used for precision motor control, positioning or mechanical displacement.
