The invention relates to a device and a method for testing a force characteristic of a linear
electric motor, which relate to the technical field of
motor test, and aims at the main problems existing in various linear
electric motor test devices at present. A pull
pressure sensor is used for testing the output force of a linear
electric motor to be tested, and is also used for testing the force applied to a rotor of the linear electric motor to be tested; a
ball screw is used for converting gyroscopic motion of a loading
servo motor into
linear motion of the rotor of the linear electric motor to be tested, and comprises a nut, a screw rod and a fixed support; the loading
servo motor is used for driving the screw rod of the
ball screw to rotate and dragging the nut of the balls screw to do
linear motion; a base is used for fixing a
stator of the linear electric motor to be tested and the fixed support of the
ball screw, so that the rotor of the linear electric motor to be tested driven by the nut of the ball screw and the
stator of the linear electric motor to be tested fixed on the base are located at a normal working position of the linear electric motor; a guide rail is used for guiding and supporting the rotor of the linear electric motor to be tested to move on the base along the
motion direction of the rotor of the electric motor; and a displacement sensor is used for measuring the displacement of the rotor of the linear electric motor to be tested.
