Beschreibung
Zusammenfassung:	A system for driving a hydraulic fracturing pump includes an electric motor having a drive shaft configured to rotate at a constant speed and a power source electrically connected to the electric motor. The system also includes a motor controller operably connected to the electric motor via a relay, wherein the motor controller is operably connected to the electric motor by the relay to start the electric motor, and is operably disconnected from the electric motor by the relay once the drive shaft reaches the constant speed. The system further includes a pump coupled to the drive shaft via a transmission, wherein the transmission is configured to transfer rotational energy from the drive shaft to the pump via an output shaft of the transmission, the output shaft of the transmission being configured to drive the pump at varying speeds while the drive shaft rotates at the constant speed.
