An alternator is an electromechanical device that converts mechanical energy to alternating current electrical energy. Alternators use a rotating magnetic field. The alternators used in modern automobiles usually generate less than 500 watts. There are two types of alternators such as the revolving armature type and the revolving field type. The revolving armature type is similar in construction to the dc generator in that the armature rotates through a stationary magnetic field. The revolving field type of alternator has a stationary armature winding and a rotating field winding. Alternators are designed for varying alternating-current frequencies between sixteen and about one hundred hertz for use with arc lighting, incandescent lighting and electric motors.
Altitude Chambers are capable of simulating altitudes up to 200,000 feet, depending upon configuration. The overall temperature range is -70ēC to +177ēC. Humidity capabilities range from 20% to 98% RH, and workspace sizes range from 5 to 64 cubic feet. Altitude chambers provide exacting performance and a high degree of reliability for your altitude testing needs. They have continuously welded, stainless steel and vapor-tight interior liners. They also have the linear pressure transducer to measure altitude and vertical-down recirculating conditioning stream.
