The main reason for the difference in output characteristics between no-load and load of permanent magnet DC tachogenerators
The magnetic field distribution of the internal magnetic circuit of the device is affected by the rotor pole position and the number of poles at no load and load. Through the query permanent magnet DC speed generator product description information, when the speed generator is in the no-load state, the rotor speed is higher, resulting in increased magnetic leakage in the magnetic field, making the stator in the winding induced electromotive force decreases, thus causing a reduction in output voltage, while when the speed generator is in the load state, the speed is lower, resulting in a reduction in magnetic leakage in the magnetic field, making the stator in the winding induced electromotive force increases, thus causing the output voltage to increase. This causes the output voltage to increase. DC permanent magnet speed generator that permanent magnet DC speed generator, is a rotor speed will be converted to electrical signals electromechanical signal components, is one of the basic components of the servo system.
