Key matching parameters between S series reducer and motor


When matching, it is necessary to pay attention to the following core technical parameters to ensure that the motor and reducer work together:

Power Range: The S series is typically compatible with motors ranging from 0.12 kW to 22 kW, with some models supporting up to 45 kW.

Number of motor poles: Supports connecting motors with 2, 4, 6, and 8 poles.

Input interface: The S series gearbox provides standardized input interfaces:

Motor flange input: The most common way is for the motor to be directly connected to the reducer through a flange.

Solid shaft input: The reducer has an input shaft that can be connected to the motor through a coupling.

Installation method: The S series gearbox provides extremely flexible installation options to adapt to different mechanical structures

S: Foot installation, solid shaft output

SA: Foot installation, hollow shaft output

SF: Flange installation, solid shaft output

SAF: Flange installation, hollow shaft output

SAT: With torsion arm, hollow shaft output
