Important points in correct and economical selection

Correct but economical choice key point
  1. Always select by "Torque" and not "Horse Power" or "KW".
  2. Always ensure that the design torque will be below the allowable output torque both at the maximum and minimum speeds.
  3. The higher the input speed is (but not exceeding 1,800 RPM), the more economically selection is made.
  4. For the limited speed range less than 6:1, selection of use at the higher output speed range is always economical.
