Title: Innovations by Eric J Mjolhus
Introduction
Eric J Mjolhus is an accomplished inventor based in Ramsey, MN (US). He has made significant contributions to the field of lubrication technology, holding 2 patents that showcase his innovative approach to energy harvesting and motor control systems.
Latest Patents
One of his latest patents is the "Lubrication injector with energy harvesting." This system is designed to harvest energy from a lubrication event and includes a fluid pump, a fluid injector, an energy harvesting device, a wireless transmitter, and a controller unit. The fluid injector receives fluid from the fluid pump and is connected to the energy harvesting device, which generates electrical energy in response to the firing of the fluid injector. This electrical energy powers the wireless transmitter, which transmits a signal indicating that the fluid injector has fired. The controller unit receives this signal and manages the fluid pump accordingly.
Another notable patent is the "Electronic pump motor control." This motor control system for a lubricant pump motor consists of a pump system power input, a motor drive, a current sensor, a lubrication controller, and a drive controller. The pump system power input supplies system power, while the motor drive operates the lubricant pump motor. The current sensor monitors the input current, and the lubrication controller provides motor activation signals. The drive controller receives these signals and controls the motor drive based on the sensed input current and a user-defined current set-point.
