(2) Feature
High-precision LVDT sensor is used for roundness measurement, combined with analog and digital filtering methods, to achieve high stability and rapid acquisition of sensor signals, and to ensure the high accuracy of sensor signals.
The stepper motor is used as the measurement drive source, combined with high subdivision and high-speed pulses to drive the motor, to ensure that the motor is smooth and continuous and the measurement points are equally spaced.
The unique commutator gap data recognition algorithm is used to ensure that the measurement result data does not include the data in the gap and the edge of the gap, and the authenticity of the measurement result is guaranteed.
It is optional to complete the inspection of the surface roundness quality of the central shaft while measuring the commutation photos to find the quality of the armature rotor more accurately.
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.

(3) 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.
(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.
