Stepper motors are the ideal solution for specific applications which require precision and
control. Though not ideal for every application, when chosen correctly, stepper motors prove to be a perfect combination of function, performance, and reliability.
Inside a stepper motor you’ll find permanent magnets located on a rotor, with windings on a fixed stator. These windings distribute magnetic flux as current flows through them, which
interact with the rotor's magnetic force distribution to produce a rotational force.
Stepper motors have a high pole count, typically upwards of fifty, or higher. The rotor rotates in a succession of steps thanks to the stepper motor driver's sequential powering of each pole. Because of this high pole count, motion has the appearance of being completely smooth.
There are several distinct advantages to stepper motors. Due to stepper motors incremental
motion, they have no need for expensive and complex encoders or resolvers.
But that's not all you can gain by employing a stepper motor, added benefits include:
High torque power
The torque power of a stepper motor is comparable to that of a similar frame-sized servo motor, however a stepper motor of the correct size and form can help save considerable costs compared to a servo motor, offering extra time-dependent peak torque power and a more flexible speed curve.
Cost of Maintenance
Due to the fact that stepper motors are brushless in their design, they require significantly less maintenance. Conventional motors, by contrast, require frequent replacement of their brushes throughout their lifetime.
Reduced complexity
If you are seeking a motor for your application that must operate with precision, the Stepper
Motor is the most appropriate motor solution for your needs. Because a stepper motor runs on an open-loop system, it does not require an encoder, making it less costly and complicated than other motors.
Repeatability
Repeatability is one of the stepper motor's most desirable properties. After rotating a full cycle, it has the ability to revert precisely to its starting point. This ability makes stepper motors incredibly precise and the best choice for applications where exact speed is demanded.
Servo Motors Vs Stepper motors
The number of poles is the primary means of distinguishing a stepper motor from a servo motor. Servo motors have fewer poles than stepper motors do, therefore if it's torque you require, stepper motors outperform servo motors on every count.
