The standard insulation of SIMOGEAR geared motors is designed such that inverter-fed operation is possible at line voltages of 400 V, 460 V and 500 V.
Depending on the line voltage, insulation systems with different insulation strengths are used as the standard insulation.
When SIMOGEAR geared motors are operated on inverters with step-up converter (ALM, AFE), the data in the table below must be observed.
