Advantages:
Thanks to their internal structure, stepper motors do not require sensors to detect the motor position. Stepper motors move by performing "steps", so simply counting the number of steps gives the motor position at a given time.
In addition, stepper motors are very simple to control. They also require a driver, but do not require complex calculations or adjustments to work properly. The control effort is usually small compared to other motors. And, if microstepping mode is used, position accuracy up to 0.007° can be achieved.
Stepper motors provide good torque at low speeds, can also hold position well, and have a long service life.
Disadvantages:
• Loss of steps may occur when the load torque is too high. Since the actual position of the motor cannot be known, this has a negative impact on control. This problem is more likely to occur when microstepping mode is used.
• Stepper motors always consume maximum current even when stationary, which reduces efficiency and may cause overheating.
• Stepper motors have low torque and generate a lot of noise at high speeds.
• Stepper motors have low power density and low torque-to-inertia ratio.
In short, when you need low cost, smooth operation, fast response, long life, and high output torque, stepper motors are a good choice.
Applications of stepper motors:
Mainly used in ATM machines, inkjet printers, engraving machines, photo machines, spraying equipment, medical instruments and equipment, computer peripherals and mass storage devices, precision instruments, industrial control systems, office automation, robots and other fields.
