Abstract
A method and system to convert a constant speed motor drive () into a variable speed motor drive () are disclosed. The method comprises disconnecting a second terminal () from a first terminal () by removing from the constant speed motor drive () a first cover assembly () comprising the second terminal (), the constant speed motor drive () comprising the first cover assembly () and a base assembly () including the first terminal (), the cover assembly further comprising a constant speed controller (), the first terminal () adapted to receive an alternating-current (AC) voltage and including motor contacts operable to output a motor voltage, wherein the constant speed controller () generates the motor voltage for the motor contacts when the constant speed controller () operates; and connecting a third terminal () to the first terminal () by coupling a second cover assembly () to the base assembly (), the second cover assembly () comprising the third terminal () and a variable speed controller () electrically coupled to the third terminal ().
