The torque required to turn a fan increases very rapidly with speed so a rheostat (or capacitor) which limits torque will reduce speed. The high rotor resistance keeps the motor from overheating at high slip. electricpete (Electrical) 28 Nov 12 20:32.

I measured the voltage going into the motor while slowly turning the rheostat from no-power to full-speed. I can see that the voltage increases in only 5 steps at 4.0, 5.3, 6.6, 8.9, and 11.2 volts.
Nettet19. mar. 2024 · This simple method of motor speed control, however, is inefficient, as it results in substantial amounts of power being dissipated (wasted) by the rheostat. A much more efficient means of motor control relies on fast “pulsing” of power to the motor, using a high-speed switching device such as a transistor. ming auto shineNettetVariable Speed Controller,SCR AC Motor Speed Control for Router Fan Electric Motor Rheostat,Voltage Controller Fit,Router Variable Fan Speed Controller 120V~220V 15A 4000W (US Plug) New to Amazon. $35.99 $ 35. 99. 5% coupon applied at checkout Save 5% with coupon.
