The electrical machines module consists of the efficiency and motor selection learning module plus learner activity slides and practitioner presentations.
The Electrical Machines module consists of three learning resources which should be completed in sequence:
- Introducing electric motors
- Investigating torque, speed and current
- Efficiency and motor selection

1. Introducing electric motors
This Level 2 resource introduces some basic classifications of DC and AC motors before exploring in simple terms what differences lead to their various characteristics and applications
2. Investigating torque, speed and current
This Level 3 resource introduces characteristic curves for DC series, shunt and compound motors, including for torque, current, speed and power.
3. Efficiency and motor selection
This Level 3 resource provides an exploration of power output and efficiency, and how this affects real-world performance.
The importance of electric motor efficiency is considered in the wider context of sustainability.
