Robots are intelligent machines used to assist humans by performing repetitive tasks and reducing instances of human error. By automating simple tasks, robots save time and money, allowing human workers to perform more complex jobs. Most robot actuation or movement relies on motors for precision and reliability.
We will explore the different types of motors used in robots and the benefits they provide for specific robotic applications.
Micro Motors and Robots
Robots with electric drives usually offer greater precision and repeatability, take up less space, and operate quietly. Micro motors deliver the high speed required in robotic applications, without compromising accuracy.
As robots grow more compact and sophisticated, micro motors are quickly emerging as an ideal type of motor. They offer speed and precision in a compact design that permits adaptability to meet the application’s unique requirements. Micro motors consume less power than other motors while providing the same level of performance and service life.
Electric micro motors can use an alternating current (AC) or direct current (DC). Robotics engineers often prefer DC motors due to their control over speed and instant acceleration. AC motors provide high initial torque but rely on AC for operation, which can be challenging for many robotics applications.
Different Types of Motors Used in Robotics
The robotics industry uses several types of motors, including servo, stepper, brushless DC, and brushed DC motors. Servo motors rely on a closed-loop system that is digitally controlled and receives speed and position information from a feedback device. Stepper motors rely on pulsed signals and can stop immediately when they receive the command, and they remain in place when power is removed.
DC motors are preferred in robotics and typically come in brushed or brushless configurations. The essential components of DC motors are a magnetic rotor and a stator with electrically conductive coils that spin the rotor using an electric current. The rotations create mechanical energy from electricity. Brushed DC motors are simple, cost-effective, and can withstand harsh conditions. The only disadvantage is that the brushes make direct contact with the commutator, causing friction that can wear out the motor over time.
Brushless DC motors rely on electric commutation rather than brushes. They can be made lighter, more compact, and longer-lasting with less wear and the same power output. Because they are more complex, brushless DC motors require a separate electronic system to control their operation.
