• Torque motors do the trick
  to frame sizes for conventional brushless-dc servomotors. For each diameter, there are several axial lengths, so engineers have a range of sizes to satisfy torque requirements for given applications. A torque motor is part of this rotary table Torque motors have been around since at least 1970...
• Linear Voltage Fan Speed Control Using Microchip's TC64X Family
  on or completely off. This efficient control methodology affords a very wide speed control range (typically 10% to 100% of full speed) because the fan motor is exposed to its full-rated voltage during the active portion of the PWM cycle. PWM control works with standard, two-wire Brushless DC (BDC) fans...
