The speed of a universal motor is generally reduced by using_________?
Correct answer: A. gear trains
- A. gear trains
- B. V-belts
- C. brakes
- D. chains
Explanation
A gear train reduces the output speed while allowing the universal motor to continue operating at its efficient high speed. Belts and chains can also transmit motion, but gearing is the standard speed-reduction method intended here.
