The coupling portfolios normally found on the market consist of comparable couplings with a maximum permissible torque corresponding to twice the coupling’s nominal torque. To be on the safe side – for example during the run-up phase of an asynchronous motor with typical starting torques and tilting moments – it is often necessary to fall back on the next-largest coupling size. If high rotational speeds or relatively large bores need to be taken into account, the market often offers
The most economical drive to use up to 50 H. P., is a high starting torque motor connected to the pinion shaft by means of a flat or V-Rope drive. For larger size motors the wound rotor (slip ring) is recommended due to its low current requirement in starting up the ball mill.

Additionally, when faced with high-power electromagnetic threats, the communication and guidance systems should have the capability of being rapidly tuned to a different frequency outside the frequency range of the threat.While various technologies, including those based on semiconductors, ferrites, mechanical devices, etc., have been proposed to address these needs, the devices based on those technologies are bulky, have generally high insertion losses, and have either slow responses or are
