Specifying a stepper motor: a guide to the key parameters

25th May 2023

Stepper motors are often perceived as more complex to specify and control compared to BLDC or brushed DC motors. However, their inherent positioning capability, converting electrical pulses to discrete ‘steps’, enables reliable incremental motion. Without the need for an external feedback device, this also aids simpler, and more compact, motion system design.

The impact of load on miniaturised motor selection

19th April 2023

When selecting a miniature motor, understanding the different loads acting on the motor is key to achieving the best design. Understanding torque load is essential to define the necessary motor power, while understanding radial and axial loads is required to achieve optimal performance and longevity through the most appropriate motion solution specification.
