How to check commutator motors

1) Check connecting blocks (wiring) and if there are any stuck out / folded terminals

2) Check if there are any water or detergent traces / remaining / deposits and where

they come from

3) Control any windings / mass particulars or with a very low ground insulation by using

a tester with minimum capacity of 40 Mohm between every single terminal and the

housing (read ∞).

4) Check every single winding according to the following table

Motor junction

box terminals

Stator winding

(half field,

terminal 1)

0.5 ÷ 1.0 0.5 ÷ 1.5 0.5 ÷ 1.0

Note: while controlling rotor winding, you have to measure all the section by rotating the shaft

very slowly and check if there are any short-circuits between the visible bars.

Check also the wear state of brushes.

P = motor-protection

R = rotor

S = stator

T = tachymetric generator
