Stepper Motor
A stepper motor, or stepping motor, is a brushless DC motor that divides a full rotation into discrete steps. It can be controlled to move to a specific position and hold that position without needing a feedback sensor, as long as it is appropriately sized for the application in terms of torque and speed.
Micro step DC motors, or micro stepper motors, are small, precise devices used in various industries. They break a full rotation into micro-steps, providing highly accurate angular movement. These motors are used in robotics, 3D printing, camera systems, and automation. They offer precise positioning, smooth motion, and excellent repeatability, making them ideal for tasks that require detailed control, such as CNC machines, linear actuators, and automated systems.

The Technology Of Stepper Motor
A stepper motor is a brushless DC motor that moves in discrete steps. This allows for precise positioning without the need for a feedback sensor, making it an open-loop system. The motor consists of a rotor, usually a permanent magnet, surrounded by stator windings. When the windings are activated in a specific order and current flows through them, they create magnetic fields that generate rotational force.
Stepper motors are controlled by electrical pulses sent to the coils. The speed and direction of the motor depend on the number of pulses received. A common type of stepper motor is the four-phase unipolar stepper motor, which has four coils energized in a sequence to produce rotation.
Common DC Motor Designs
No matter which DC motor technology is used, certain form factors and design features are common across many industries. These shared elements help guide the selection of the best motor solution. Below are some examples to help describe your ideal choice.
Terminals and connector pins
Connecting the motor to the application is essential. We usually use soldered pins, spring pad connectors, and integrated connectors for this purpose.
Leads and connectors
Wires and leads are commonly used to connect motors in applications. We provide various lengths, gauges, and pre-installed connectors.
Frame modifications
Securing motor frames to your application can be achieved in several ways. Custom fastening points and brackets are often utilized.
EMI filters and backpack PCBs
Operating motors generate EMI electrical noise. This can be reduced by installing filters, which can be either PCB-based or wire-based.
Shaft modifications
The motor must connect mechanically to your product. We can create custom shafts and pre-install gears, bushes, and bosses.
Motion controllers
A small PCB attached to the back of a DC motor can convert it into a precision servo at a fraction of the cost of a similar off-the-shelf unit.
