I agree with Sidewinder, but would also add DC motors and controllers. As they still used in some industries and are more common than you may have been lead to believe (we use 450ADC motors). Think of AC motors like petrol engines (high torque at high speeds), and DC motors like diesel engines (high torque at very low speeds). Plus, learn about the different analogue signal types used in Industry for control (i.e. 0-20mA, 4-20mA, 0-10V, 0-50VDC, 0-100VDC, 0-200VDC etc. and different encoders using square wave outputs). There a lot more you will need to know to become an industrial electrician. Anyone expecting to be paid £38k, should be well versed in all the aforementioned aspects of industrial electrical theory and practise. And BS7671 still applies such as colour codes of wiring. That why there additional colours listed in table 51 for ELV control circuits, such as orange that has a very particular meaning in industrial control systems.
If you enjoy electrics, rather than it just a means to an end (i.e. to ern money). Then industrial systems far more challenging, but also very rewarding.
Good luck
