A suitable motor can be selected from the "Built-in torque motors: overview" table in
accordance with the following criteria:
Maximum torque of at least 55 Nm.
Maximum speed (specifying the max. torque): at least 80 rpm.
Suitable motors include:
1FW6053-0PB05-0FC2 (outer diameter 159 mm, length 109 mm)
1FW6063-0PB03-0FC2 (outer diameter 184 mm, length 82 mm)
The moment of inertia of the motor 1FW6053-0PB05-0FC2 is J = 0.00267 kgm
The accelerating torque M
M
= (1.5 kgm
a
This means that the total motor torque required increases M
The moment of inertia of the motor 1FW6063-0PB03-0FC2 is J = 0.00347 kgm
The accelerating torque M
M
= (1.5 kgm
