FAQs

Choosing or specifying a motor controller raises many practical questions. Which control method suits your motor? Can an off-the-shelf drive do the job, or do you need something custom? What does a development project involve, and how does it move into production?

These FAQs draw on our experience designing and manufacturing brushless DC, stepper and asynchronous motor controllers for OEM customers. They cover the questions engineers and buyers ask us most often: control techniques such as sensored and sensorless BLDC, field-oriented control and microstepping; driving demanding motors, including low-inductance and high-speed designs; and how our custom motor controller design and manufacturing services work in practice.

As a UK designer and manufacturer working on a high-mix, low-volume basis, we regularly help customers with projects that don't fit a standard catalogue product. Browse the questions below, or read our technical articles for more in-depth guidance.
