Tons to kW conversion calculator How to convert kW to tons. One refrigeration ton is equal to 3.5168525 kilowatts: 1 RT = 3.5168525 kW. One kilowatt is equal to 0.284345 refrigeration ton: 1 kW = 0.28434517 RT . So the power P in refrigeration tons (RT) is equal to the power P in kilowatts (kW) divided by 3.5168525: P (RT) = P (kW) / 3.5168525
Electric-car Motors and Batteries. Electric cars can use AC or DC motors: If the motor is a DC motor, then it may run on anything from 96 to 192 volts. Many of the DC motors used in electric cars come from the electric forklift industry. If it is an AC motor, then it probably is a three-phase AC motor running at 240 volts AC with a 300 volt
The electric chain hoist consists of motor, transmission mechanism and chain wheel. The biggest difference between the electric chain hoist and the electric wire rope hoist is that the wire rope is replaced by the chain. The lifting capacity is generally 0.5-60 tons, and the lifting height is 3-120 meters. Contact us for AICRANE electric hoist!

DC Motors 1. Shunt DC motor: The rotor and stator windings are connected in parallel. 2. SparatelyExcited motor: The rotor and stator are each connected from a different power supply, this gives another degree of freedom for controlling the motor over the shunt.
coil, we must account for the sensible and latent heat. The term “Enthalpy” is used to describe the total heat of a substance. The enthalpy of a substance is the sum of the sensible heat and latent heat contained in that substance. It is expressed in BTU/lb and is normally designated by “H”. For air, enthalpy is expressed in BTU/lb of

The change in kinetic energy, the power output, and the turbine inlet area are to be determined. Assumptions 1 This is a steady-flow process since there is no change with time. 2 Potential energy changes are negligible. 3 The device is adiabatic and thus heat transfer is negligible. Properties From the steam tables (Tables A-4 through 6) 1 3240
