These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Motors can be used to create movement in a control system.
- A current carrying wire in a uniform magnetic field is forced to move, we use this movement to make motors.
- DC motors are most suitable for applications where continuous rotation is needed.
- Servo motors control position, speed, and torque. They are suitable for applications where precision is required.
Keywords
Direct current - the electric current flows in one direction only
Torque - a force that makes something rotate
Servo motor - a motor that uses a closed-loop system to ensure accurate and precise control of their position, speed, and torque
Uniform magnetic field - a magnetic field that has the same strength everywhere with evenly spaced field lines
Common misconception
All motors operate in the same way.
DC motors use open-loop systems, and servo motors use a closed-loop system.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
