Commutator Roundness Electric Motor Testing Equipment For Brushed DC Motor

Commutator Roundness Good Communication Testing Device For Brushed DC Motor WIND-RM-10

(1) The purpose commutator roundness testing

If the commutator is not round, this increses the chances of incresed brush wear on the brushed DC

motor armature, as well as an increase in arcing and sparking of the commutator thereby destroying the

commutator surace, Good commutator roundness is very important for the armature performance.

(2) Features

1. The high precision LVDT sensor is used for the roundness measurement, combining the analog and

digital filtering method into realization a high stability and rapid access to the sensor signal, to ensure

the high precision of the sensor signal.

2. Stepper motor is used as a driving source of measurement,combined with motor driven high subdivision

and high-speed pulse, ensuring the motor to run as smooth continous and measurement points

equidistant distribution.

3. The commuatator slot data recognition algorithm is unique, to ensure that the measurement results of

the data dones not include the gaps and the gap edge data, to guarantee the authenticity of the

measurement results.

4. When it measured on commutator bar also complete the detection of roundness quality surface to the

center axis at the same time, to find more accurate qualtiy armature.

(3) Technical Data

(4) Competitive Advantages

1. Commutator surface turning quality is one of the importand factors that infulence the performance

of armature, timely check the turning qulaity of commutator can provide an effective means of control

the lathing quality.

2. The WIND-RM-10 Rotor roundness tester can deteck the armature commutator roundness fast and

accurately, it is a fast and direct way to know the state of the armature production, can control the

product quality timely, control the production process and ensure the armature manufacturing quality.

3. High precision, no rust, rust, acid and alkali, no magnetization, no deformation, good wear resistance,

the marble is used as a placement platform, V seat is placed on the marble platform, and the placement

accuracy of the V seat is enhanced. The components (and connecting rod driving parts) drive the rotor

(and the connecting rod drive parts) with two pairs of leveraged linkage lever mechanism synchronous

clamp Tight rotor ensures smooth rotation of the rotor, ensuring the accuracy of the test.

In conclusion, the utility model improves the automation degree of the rotor roundness tester in the

existing technology, improves the production efficiency, saves the manpower,

and improves the testing accuracy of the roundness tester.
