Structure of the selection tables

The following two figures show the structure of the selection tables for gearmotors.

There are two types of selection tables:

For standard output speeds, sorted by the rated power P_m of the driving motor in kW.
For extremely low output speeds (always compound gearmotors), sorted by the maximum permitted output torque M_{a_max} in Nm.

For drives for extremely low output speeds (compound gearmotors), the motor power must be limited according to the maximum permitted output torque of the gear unit.

Table for normal output speeds:

[1]	Rated power of driving motor
[2]	Output speed
[3]	Output torque
[4]	Gear unit ratio A value marked with * indicates a finite gear unit ratio.
[5]	Permitted overhung load on output side at M_a Overhung load for foot-mounted gear units with solid shaft; overhung loads for other design types on request
[6]	Service factor
[7]	Gear unit type (example figure)
[8]	Motor type (example figure)
[9]	Mass

Table for extremely low output speeds (compound gearmotors):

[1]	Maximum permitted output torque
[2]	Output speed
[3]	Gear unit ratio A value marked with * indicates a finite gear unit ratio.
[4]	Permitted overhung load on output side at M_a Overhung load for foot-mounted gear units with solid shaft; overhung loads for other design types on request
[5]	Gear unit type (example figure)
[6]	Motor type (example figure)
[7]	Mass
