Abstract
The utility model provides a test motor counter potential is with equipment of transmission connection which characterized in that includes frame, universal joint, fixes driving motor in the frame, sets up motor layer board in the frame, sets up the bandage in the frame, and universal joint one end is connected with the driving motor pivot, and the universal joint other end is provided with axle connecting structure. Compared with the prior art, the utility model, have the simple installation, need not accurate with the axial lead just can be fast with the fixed and with the power take off advantage of being connected of transmission motor's of the measured motor that needs the test back emf.
Description
Technical Field
The utility model relates to a motor technology.
Background
When new energy automobiles are more and more popular, the demand of motors is more and more, the production efficiency of a motor factory is also required to be higher, but the production speed is high, and the quality cannot be lacked. The no-load counter electromotive force is an important parameter of the motor performance, the counter electromotive force refers to the electromotive force generated by the trend that the counter current changes, the higher the counter electromotive force is, the higher the corresponding peak torque is, but the better the counter electromotive force is, the higher the counter electromotive force is, the controller can be burnt out, and meanwhile, the cost is increased, so that a standard interval is required, and equipment testing is required. The back electromotive force of the existing large motor is fixed on a rack by screws, the center is aligned, and a dynamometer drives the motor to rotate, so that the no-load back electromotive force is measured, and the link wastes time and is not suitable for being tested in a production workshop.
Disclosure of Invention
The invention aims to provide the equipment for the back electromotive force transmission connection of the test motor, which is simple and convenient to install, can quickly fix the tested motor needing to test the back electromotive force without accurate coaxial lead and is connected with the power output of the transmission motor.
The utility model discloses a realize like this: the universal joint comprises a rack, a universal joint, a driving motor fixed on the rack, a motor supporting plate arranged on the rack and a binding belt arranged on the rack, wherein one end of the universal joint is connected with a rotating shaft of the driving motor, and the other end of the universal joint is provided with a shaft connecting structure.
When the device is used, a motor to be tested is placed on the motor supporting plate and fixed through the binding band, then the rotating shaft of the motor is connected with the other end of the universal joint through the shaft connecting structure, the three-phase line of the motor to be tested is connected with the oscilloscope, the controller is started, the rotating speed of the driving motor reaches a constant 1000rpm (the speed is not too high, and whether the performance of the motor is qualified or not can be reflected when the motor is at 1000 rpm), and therefore the no-load back electromotive force of the motor to be tested can be tested. Because the universal joint is a part for realizing variable-angle power transmission and is used for changing the position of the transmission axis direction, the axis of the tested motor and the axis of the driving motor can simultaneously rotate at different positions, and when the no-load counter electromotive force is measured, the force driven by the driving motor of the tested motor is very small, the tested motor can be sufficiently fixed only by being tightly bound by a binding band, the tested motor can be quickly installed without installing screws, the efficiency is high, and the counter electromotive force of the motor is quickly tested.
Compared with the prior art, the utility model, have the simple installation, need not accurate with the axial lead just can be fast with the fixed and with the power take off advantage of being connected of transmission motor's of the measured motor that needs the test back emf.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings and examples:
as shown in the figure, the utility model discloses a frame 1, universal joint 2, fix driving motor 3 in frame 1, the motor layer board 4 of setting in frame 1, the bandage 5 of setting in frame 1, spline switching frock 6 (the inside wall has the cover with the spline groove that the spline on the 3a of driving motor pivot corresponds) is passed through to 2 one end of universal joint is connected with 3a of driving motor pivot, the 2 other ends of universal joint are provided with shaft connection structure an, shaft connection structure an includes flange 7, with 7 fixed connection's of flange spline switching frock 7 (the inside wall has the cover with the spline groove that the spline on the motor A pivot A1 that is surveyed corresponds). By adopting the flange 7, the corresponding spline switching tool 7 with the flange can be conveniently replaced according to the tested motor A with different sizes.
