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.

(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.
