Motor Sizing Calculations

The table H radial load values calculated considering a life of: - 20000 hours for 2-pole motors - 40000 hours for 4 6 8 poles motors with a frequency of 50 Hz For use at 60 Hz the values must be reduced by 6% to obtain the same life time For two-speed motors consider higher speed The point of application of BR must be included in the shaft

Electrical Thumb Rules You MUST Follow (Part 1)

1 Phase Motor draws Current = 7Amp per HP Full Load Current of 1 Phase Motor = HPx6 I think full load current of 1 phase is too high for examples in catalog of manufacture current of 1 phase motor 4HP only about 12A Moreover please clarify why percent of draw current and full load current is small (7/6) as i know that factor is 3/1

QIBR_CAT_E1254f_138

The basic dynamic load rating is defined as the constant load applied on bearings with stationary outer rings that the inner rings can endure for a rating life of one million revolutions (10 6 rev) The basic load rating of radial bearings is defined as a central radial load of constant direction and magnitude while the basic load rating of thrust bearings is defined as an axial load of

Solid

Nov 01 1999Kawashima et al tested MoS 2-lubricated bearings in high radial load conditions and concluded that the safe wear life is specified as being 2% of the basic rating life The bearings that had shown excellent tribological performance in light axial load conditions in vacuum [10] were examined under high axial load conditions [21]

The Electrical Distribution Architecture

The sensitivity of circuits to disturbances determines the design of shared or dedicated power circuits Indeed it is better to separate "sensitive" loads from "disturbing" loads E g : separating lighting circuits from motor supply circuits This choice also depends on operating features

Electrical termination

In electronics electrical termination is the practice of ending a transmission line with a device that matches the characteristic impedance of the line Termination prevents signals from reflecting off the end of the transmission line Reflections at the ends of unterminated transmission lines cause distortion which can produce ambiguous digital signal levels and mis-operation of digital systems

Crankshaft

A crankshaft is a rotating shaft which (in conjunction with the connecting rods) converts reciprocating motion of the pistons into rotational motion Crankshafts are commonly used in internal combustion engines and consist of a series of cranks and crankpins to which the connecting rods are attached The crankshaft rotates within the engine block through use of main bearings and the crankpins
