Description

technical field [0001] The invention relates to the field of testing force actuators, in particular to a testing device and testing method for an electromagnetic torquer. Background technique [0002] As a force actuator, the electromagnetic torquer has a wide range of applications, such as thrust components for spacecraft, force balance mechanisms for quartz flexible accelerometers, etc. The performance of the electromagnetic torquer has an important influence on the attitude control of the spacecraft, especially on the measurement accuracy of the quartz flexible accelerometer. [0003] In the existing electromagnetic torquer testing methods, the electromagnetic torquer is only used as a component of the system under test, and is tested together with other components as a whole. The test results cannot be used to evaluate the characteristics of the electromagnetic torquer alone. In addition, the test input is based on the gravitational component. In the test of the quartz...
