My 1924 mercury vacuum barometer left to me by my grandfather broke in transit from the United Kingdom to Australia. The original operating principle is an evacuated glass tube in a U shape that holds mercury in the base of the U. As the pressure cha...
With new drivers, new teams, new circuits, a new title sponsor and broadcast deal it is a new dawn for the IndyCar Series as it speeds towards a future that could again include international races. These are bullish times at IndyCar headquarters with...
There are several types of AC (e.g. induction, synchronous) and DC (e.g. series, shunt, permanent magnet) motors. Each of those types can be designed (within some constraints) to have different torque-speed relationships. In North America, AC inducti...
Compressed air motors exist, and can be used to drive a car without electric power at all. I have actually ridden in a compressed air powered car One of those, quite possibly that actual vehicle. It works, but it isn’t a fantastic solution, and elect...
Direct drive means that the motor connects directly onto the back of the drum shaft, traditionally this was done by using a belt. Inverter means that there is an electronic drive control system between the incoming power supply and the outgoing power...
A carrier condenser fan motor HC39GE238 plays a vital role in the performance of an HVAC system. Its function is to cool the hot, refrigerant gas to a cool liquid. Most of the carrier condenser fan motors today are a single speed although some ultra ...
Direct drive motors are far more efficient than an equivalent belt drive motor. Direct drive motors, sometimes called pancake motors, are synchronous motors which operate by variable speed 3-phase A/C. The stator contains the 3-phase windings, and th...
An induction motor can be used as an induction generator too. You can also make one in your home too. For induction motor you can use a fan (exhaust fan or stand fan). To make an induction motor a induction generator, you China wall fan motor Manufac...
