Tekst:

The burning smell is most likely coming from the main power resistor on the speed control circuit.   It is a 450 ohm, 15 Watt, wirewound resistor which becomes quite hot in use - more so at low speed.  A slight odour is not a fault.

Sparking from the motor brushes and/or speed control contacts can also result in a slight electrical smell.  If the machine has been heavily used it could be worthwhile getting the motor cleaned and serviced to prolong life.
