Machine Parts

  The electrical machines are used as the prime mover to achieve the operational movements of a machine tool. But the performance characteristics of the driving motor is satisfy not only the operational conditions but also the requirement of cooling the machine tools. If a clutch is set between the motor and the gear box, the motor can be started under no load condition. In its absence of high starting torque is required to overcome the resistance and the inertia. The operation movement and the kinematic linkage the driving motor may be run in two ways   a.        At a constant speed. b.       With stepped variable speed. c.        At two constant speed. d.       With infinitely variable speed.   It also can run in forward direction or reserve direction.   The working condition also influence the selection of an electric motor. These are open, protected, splash proof, dust free etc and to possibility to assemble it in a machine tool
