An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix. They are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, generators, inductors, electromagnets, transformers, solenoid valves, and sensor coils. Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely an external timevarying magnetic field through the interior of the coil generates an EMF voltage in the conductor. In refrigeration, the condenser coil dispels hot air to the outside of the space. The refrigerant then loops back to the compressor, gets cold again, absorbs heat and disperses it to the outside. As long as the compressor is running, the refrigerant keeps up this continuous loop. Extracting heat from the space and transferring it to the refrigerant is the function of the evaporator coil. A gear or cogwheel is a rotating machine part having cut teeth or, in the case of a cogwheel, inserted teeth called cogs, which mesh with another toothed part to transmit torque. Geared devices can change the speed, torque, and direction of a power source. Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a transmission. A gear can mesh with a linear toothed part, called a rack, producing translation instead of rotation. Motors are used in all kinds of restaurant equipment to power beaters, blenders, slicers, basket lifts, filters, fans and much more. A motor converts one form of energy into mechanical energy. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air. A motor is a device driven by electricity, air, or hydraulic pressure, which does
