The force does not equal the power, and the force density that is high does not equal the power density that is high!
Power is force times velocity. Magnetic saturation density and current intensity limit the electromagnetic force but do not limit the speed of the electric drive. Due to the limitations of moving part

Superconductors
Superconductors, with almost zero resistance, could theoretically pass through an enormous electricity current, reducing the volume and mass of the electromagnetic actuator and further incre

The root cause for using hydraulic transmission
For fixed devices, electrical energy is generally available directly. Therefore, hydraulic transmission is not the first choice and is the last resort that will be used. But hydrau

The case for transmission modes
To compare different transmission modes in practical application, the cost is usually very high. Because, it not only must do the paper rehearse and make the correspondin

The competition of transmission technology
Although hydraulic technology is only a transfer of mechanical energy rather than the generation of mechanical energy technology. Just like the transport industry, it is only the transf
