Line interfaces: Upstream
Confirm motor frame, input speed, connected load in kW, three-phase supply if a gearmotor is quoted, and whether a brake or encoder already exists. Upstream documents should not assume a helical parallel-shaft envelope will fit a bevel housing.
Control boundary
Mounting position determines lubrication and breather arrangement. Ask the factory to return the oil quantity and breather location for the installed orientation, plus whether cooling water or a fan is required for the stated duty cycle. Nominal catalog speed is not a validated plant output; request the test conditions that sit behind any throughput claim on the driven machine.
