The invention relates to a method () for starting an electric single-phase induction motor (), wherein during a start-up interval of the start-up cycle for starting said electric motor (), the frequency (f) of the electric current for driving said electric motor () is set to a first frequency (f), and later to the operating frequency (f) of the electric motor (), wherein the first frequency (f) is higher than the operating frequency (f).

Method for starting a single-phase induction motor

Embodiments of the invention provide a variable frequency drive system and a method of controlling a pump driven by a motor with the pump in fluid communication with a fluid system. The drive system and method can provide one or more of the following: a sleep mode, pipe break detection, a line fill mode, an automatic start mode, dry run protection, an electromagnetic interference filter compatible with a ground fault circuit interrupter, two-wire and three-wire and three-phase motor compatibility, a simple start-up process, automatic password protection, a pump out mode, digital input/output terminals, and removable input and output power terminal blocks.
