2. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

3. Brushless DC electric motor - Wikipedia

   en.wikipedia.org/wiki/Brushless_DC_electric_motor

   DC brushless ducted fan. The two coils on the printed circuit board interact with six round permanent magnets in the fan assembly. A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply.

4. Induction generator - Wikipedia

   en.wikipedia.org/wiki/Induction_generator

   For a machine to run as an asynchronous generator, capacitor bank must supply minimum 4567 / 3 phases = 1523 VAR per phase. Voltage per capacitor is 440 V because capacitors are connected in delta. Capacitive current Ic = Q/E = 1523/440 = 3.46 A Capacitive reactance per phase Xc = E/Ic = 127 Ω. Minimum capacitance per phase:

5. Load bank - Wikipedia

   en.wikipedia.org/wiki/Load_bank

   The most common type uses wire resistance, usually with fan cooling, and this type is often portable and moved from generator to generator for test purposes. Sometimes a load of this type is built into a building, but this is unusual. [4] Rarely a salt water rheostat is used. It can be readily improvised, which makes it useful in remote locations.

6. Motor soft starter - Wikipedia

   en.wikipedia.org/wiki/Motor_soft_starter

   Compact soft starter for a 3 phase machine, 15kW/10HP. A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up.

7. Synchronous condenser - Wikipedia

   en.wikipedia.org/wiki/Synchronous_condenser

   The reactive power produced by a capacitor bank is in direct proportion to the square of its terminal voltage, and if the system voltage decreases, the capacitors produce less reactive power, when it is most needed, [2] while if the system voltage increases the capacitors produce more reactive power, which exacerbates the problem. In contrast ...
