Embodiment Construction

[0023] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0024] Such as Figure 1 to Figure 4 As shown, a motor test device includes a fixed shaft sleeve 1, a fixed fan blade 2 and an adjustable fan blade 3. The center of the fixed shaft sleeve 1 is provided with a motor shaft insertion hole, and the fixed fan blade 2 and the adjusted fan blade 3 are four Right (i.e. eight), four pairs of fixed fan blades 2 are arranged on the fixed shaft sleeve 1 and are evenly distributed along the circumferential direction of the motor shaft insertion hole axis. The fixed fan blades 2 are correspondingly stacked, and the adjustable fan blades 3 can move relative to the fixed fan blades 2 .

[0025] Among them, the fixed shaft sleeve 1 is evenly distributed with fixed ribs 5 in the circumferential direction, and the fixed ribs 5 are provided with a fixing part for fixing the fan blade 2; the fixed shaft sleeve 1 is provided with ...

Abstract

The invention discloses a motor test device, which comprises a fixed shaft sleeve, fixed fan blades and adjusting fan blades, wherein a motor shaft insertion hole is arranged in the center of the fixed shaft sleeve; at least two fixed fan blades and at least two adjusting fan blades are arranged; the at least tow fixed fan blades are arranged on the fixed shaft sleeve and are evenly distributed along the circumferential direction of the motor shaft insertion hole; and each adjusting fan blade is arranged on the fixed shaft sleeve or the fixed fan blades, is arranged corresponding to each fixed fan blade in an overlying way, and can move relative to the corresponding fixed fan blade. The motor test device has a simple structure, is convenient to use, and is very practical for test occasions with low requirements.

Description

technical field [0001] The invention relates to a motor testing device. Background technique [0002] The power of the motor is an important parameter that needs to be considered in the design of the motor. During the design process, it is often necessary to compare different motor powers. The currently used motor power testing equipment is mainly a hysteresis dynamometer, which has a complex structure and is not very practical for simple motor power testing. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a motor testing device. The present invention is simple in structure, easy to use, and very practical for testing occasions with low requirements. [0004] Its technical scheme is as follows: [0005] A motor testing device, comprising a fixed shaft sleeve, a fixed fan blade and an adjustable fan blade, the center of the fixed shaft sleeve is provided with a motor shaft insertion hole, there...
