What are DC Motors and Stepper Motors
A stepper motor does not rotate in a continuous manner, but moves in discrete steps, or increments. Stepper motors are ideal for applications that require precise positioning and repeatability, as well as fast response to starting, stopping, reversing, speed control, high holding torque, and low acceleration.
Another key feature of a stepper motor is its ability to hold the load steady once the desired position has been reached. They are widely used in industrial control applications. In a stepper motor, the input is in the form of electrical pulses and the output is in the form of mechanical motion, which is inherently unobtrusive. It provides control as an advantage over mechanical power generation and should be used if accuracy is a major concern.
A DC motor is also an electromechanical device that uses the interaction of a magnetic field and a conductor to convert electrical energy into rotational mechanical energy. These motors are from has been around since the 1830s, so has been used in a variety of applications. They're relatively cheap to buy and install, reliable and controllable, and have hundreds of ratings. Due to their improved operating characteristics, DC motors are still best suited for applications that require constant torque across the motor's speed range. It is a fast and continuous rotation motor primarily used for anything that needs to spin at a high number of revolutions per minute (RPM).
The difference between DC motor and stepper motor
DC motors and stepper motors Both motor devices are designed for use in many areas of industry, so the difference between DC motors and stepper motors can be confusing. Choosing between a DC motor and a stepper motor can be a daunting task. Several factors play a vital role in selecting the ideal electric motor device for an application. Here we compare some attributes between these two. First is the nature of the loop: stepper motors operate in open loop, while DC motors operate in closed loop.Efficiency: Whenever,When the stator poles are energized, the stepper motor will consume current at maximum load, thereby reducing energy utilization and heat loss.so，Stepper motors are not the best choice if efficiency is a concern.butDC motors are a mature technology and can achieve efficiencies around85%, which is good for such a simple motor.
