It was founded by Dr. Stanton Allen and Lynde Bradley with an initial investment of $1000. [2] In 1904, 19-year-old Harry Bradley joined his brother in the business, and the company's first patented product, a carbon disc compression-type motor controller for industrial cranes, was demonstrated at the St. Louis World's Fair the same year. In ...
A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network ...
The starter motor is a series, compound, or permanent magnet type electric motor with a solenoid and solenoid operated switch mounted on it. When low- current power from the starting battery is applied to the starter solenoid, usually through a key -operated switch, the solenoid closes high-current contacts for the starter motor and it starts ...
