Anokiwave
Enabling High Capacity Satellite System Terminals msec. This technology is arguably best for TV 's, radios, and weather communications, and broadcast services. In comparison, the LEO satellites orbit 500 km to 1,500 km from earth. These satellites are much smaller, cost less to manufacture and to launch. Their life cycle is shorter and in order to have global coverage, there is a need for many of them. These satellites are moving at a much faster pace because of their proximity to earth and a larger number of them will be required to cover... (read more)Browse Antennas Datasheets for Anokiwave -

Essen Magnetics Pty Ltd
Motor (Rotor and Stator) The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor 's axis. The stator is the stationary part of a rotary system, found in electric generators, electric motors, sirens, mud motors, or biological rotors. Energy flows through a stator to or from the rotating component of the system. In an electric motor... (read more)Browse Motor Coils Datasheets for Essen Magnetics Pty Ltd -
