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 not change the chemical composition of its energy source. Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase see singlephase, twophase, or threephase, and may be either aircooled or liquidcooled. Generalpurpose motor designs with standard dimensions and characteristics provide convenient mechanical power for foodservice equipment once customized to the exact OEM specifications RPM, torque, magnet dimension, winding, etc.. A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage e.g. in a pump system, containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets or orings. A shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power. The various members such as pulleys and gears are mounted on it. Specifications. Height 0.15 in.. Width 1 in.. Length 1 in.
