2.3 Motor and belt
See the instruction manual for the motor to be
used and install the motor properly.
To install the clutch motor, align the center of
the machine pulley with that of the motor pul-
ley when the motor pulley shifts to the left with
toeing down the pedal.
NOTE: Table 2 shows the outside diameter of the
motor pulley, sewing speed of the machine,
and size of the belt when using the clutch
motor of 3-phase, 2-pole, 400W(1/2HP).
The outside diameter on the table shows
the nearest size to the calculated values
based on the commercial pulleys at inter-
vals of 5 ㎜ .
Fig. 2-9
Table 2
Use only those motor pulleys applicable to the machine.
If not, the sewing speed will be over maximum and it can
cause the machine to damage.

Table 3
Servomotor:
Calculate the outside diameter of a motor pulley
from the formula as below.
Or see Table 3 to select a proper motor pulley
diameter.
Outside diameter Usual sewing speed
of motor pulley Servomotor speed
= ×48.5 + 5 mm
Belt
Use a V-belt of M type.
For belt size, refer to Table 2.
