RPM control sensor

The BLDC motor of the Magnetic Generator is designed to withstand various loads and maintain its RPM regardless of external conditions. It has a build-in RPM control sensor that is used to monitor rotation of the motor shaft and prevent it from deviating from the operational limits (± 5rpm from default). Maintaining RPM is crucial for the system to operate within necessary voltage generating limits as even slight deviation from the set limits will result in failure and burnout of the PCB components. The drum of the generator is driven by the BLDC motor through pulse-width modulation of the software driver in accordance with a specified algorithm. In case of an error of the processing algorithm and deviation from the rotation limits, the RPM control sensor will automatically shut down the whole system as it is an autonomous apparatus and is independent from the algorithm. The generator’s display will present the error and provide solution for it.

Temperature sensors

There are several temperature sensors installed inside the Magnetic Generator. Each sensor is used to measure ambient temperature around generator’s windings and coolant of the device. The generator emits heat insignificantly but truly, that is why it is equipped with a forced cooling system to deliver the generated heat from internal components to the radiator at the back of the device. Once one of the sensors detect rise of temperature the cooling system will circulate coolant through the ductwork and run the radiator fan to dispose it outside. In case if temperature of any of the components keeps rising the correspondent sensor will shut down the device and the generator’s display will present an error.

Bearing noise sensors

Annual maintenance of the generator is most of all depends on lifecycle of its bearings and other moving components. Being the main source of frictional forces between the motor and its shaft it is crucial that bearings are always greased or replaced when needed. In order to perform maintenance at the right moment, bearing noise sensors are used to detect any significant noise or vibration level deviation from the recommended by the manufacturer limits. When life of a bearing comes to an end or it needs additional grease the sensors will display a message of an upcoming maintenance to the user. If noise generation exceeds maximum limit the sensors will shut down the device to prevent other moving components from damage.

Unauthorized access sensors

The Magnetic Generator is physically protected from an unauthorized access by various methods, one of which is detection of the external case opening. Each side of the generator is equipped with several motion detection sensors which serve to prevent people from opening the device. In case if one of the sensors detects the opening it will automatically shut down the device and will not let it start until an authorized person activates it.
