摘要
The invention consists of a magnetic dipole (1) set on the rotational shaft of a magnetic mass (4), a variable resistor (14) for fixing the nominal power level, a coil (10) with variable self-induction coefficient for fixing the nominal power regime, and a variable air gap (5) for adjusting the resistive torque induced on the shaft (2). A means (13) measures the frequency of the induced current, and therefore the rotational speed of the shaft (2), and the power of the said current and therefore the value of the torque on the said shaft. The device according to the invention measures low to very high rotational speeds, and measures the moment of the torque or generates a torque of from low to medium power. IMAGE
