This type of motor is used in the Pfaff 260 (-261) sewing machine. In com-
pliance with safety regulations, the PE 260 motor is enclosed in a plastic
housing (see note on insulation
on page 30).
Its principal components are as
follows:
1. Stator
2. Motor with commutator
3. Housing section (drive end), with powder-metal bearing and screwholes
for mounting it on the motor bracket
4. Housing section (opposite end), with powder-metal bearing and brush-
holder
5. Carbon brushes
When operating at 7,500 r.p.m., the motor has an output of 45 watts which
guarantees a minimum sewing speed of 1,500 s.p.m.
