Stepper motors have distinct advantages over other motors. These advantages are linked to precision control factors as well as their relatively low cost. Stepper motors have many applications in both high technology and in hobbies such as robotics and remote cars. What Are Stepper Motors? Stepper motors are a relatively new phenomena in the world of motors. The earliest motors were merely coils of wire with an electric current that spun in the presence of a magnet. Stepper motors introduced precise speed and control of the motor position through the use of microprocessors. Since the motor moves from location to location in steps, the motor became known as the "stepper motor." Applications The stepper motor allows synchronization of a motor, which may not seem like a big deal until you realize that there are numerous applications for such a motor. The synchronization of a stepper motor controller allows factories to precisely control the flow or output produced by a motor, allows robots to move with precision, and allows control and positioning of things like cameras. It also is used for rotational speed control. Another way to use stepper motors is in remote-controlled applications. Why Use a Stepper Motor? Other motors, such as the brushless DC motor, do not offer the fine control of the stepper motor. But one advantage that they do have over stepper motors is their lower cost. Other motors also have the added advantage of not requiring a microprocessor for their control, as the added complexity can create downtime and expense for businesses and hobbyists. Cost and Efficacy Even though stepper motors use more electricity because of the numerous magnetic positions involved, and thus incur a greater cost for the user, the high number of magnets isn't necessarily a bad thing because they also create a more powerful, high torque motor at low angular velocities. This makes the motor useful for many hobbyist applications, especially for builders of automated systems and robots. Builders of robots tend to favor this type of motor because it allows precise control over the position and speed of movement, and is easily controlled by a microprocessor . |
