Decoding the Perfect Match: Stepper Motor
Advice from Duron Industries leading motor expert
Our experts suggest using a stepper motor for projects that require more accurate positioning. A stepper motor is an electro-mechanical device that converts electrical pulses into discrete mechanical movements, unlike conventional electric motors, that rotate continuously. Stepper motors have a higher level of accuracy and are used in robotics, automation, CNC machines, and 3D printers.
When we choose a stepper motor for a project, we consider the principles of operation, advantages, limitations, and the motor’s construction, electromagnetic design, and number of phases. Their ability to provide precise and controlled motion makes them valuable in various industries. Let our experts at Duron Industries help you find the right stepper motor for your current or next project.

Key Features and Operating Principles
Stepper Motor System
The key elements of a stepper motor include a Motor and Driver. A stepper motor is typically powered by DC systems, but some AC Synchronous Motors for better performance.
Feedback System
There is no feedback system in a stepper motor application. It is an open-loop system that relies on the sequence and timing of the electrical pulses to move to the desired position.
Control System
The control circuit (controller/driver) sends pulses to the motor. The goal is to control speed and position. The control circuit software will adjust for any errors by indexing from it's home position.
Gear System
Many stepper motors include a gear system with different torque characteristics depending on the operating speed. At low speeds, stepper motors typically provide high torque, making them suitable for low power applications. However, torque decreases as speed increases.
Benefits Outweigh the Limitations
Stepper motors offer many impressive benefits, however, these features also make it a common system.
Advantages
Simple Control System
Low System Cost
Reliability
Bipolar (High Torque, 1 coil per phase , 4 wires, )
Unipolar (Low Power, 2 coils per phase, 6 wires)
Limitations
No Feedback for positioning
Runs at higher temperatures
Stepper motors provide simplicity and reliability making them suitable for low power and torque systems for various industries and applications. These advantages are important for choosing the right motor type for your project.
