I have a small electric induction motor which is suddenly not spinning up to it's normal speed - I reckon maybe half power. Power supply would appear to be fine, bearings are free and the motor is capable of spinning freely. There is what I would describe as a lack of torque in the motor, but this is a perception rather than anything with any real substance behind it.
Any ideas - is this the brushes in the motor worn out or similar? Sound familiar - terminal or fixable? Any info much appreciated.
