Siemens three-phase motors

IP55 is the standard degree, which covers dust and moisture in most industrial settings. IP56 and IP65 builds are available where there is heavier dust or the motor is exposed to water. Tell us what the motor has to put up with and we will specify the degree against it rather than assume the standard build will do.

Foot-mounted motors suit stable installations where the motor is bolted to a bed or frame. Flange mounting is the choice where the drive is transmitted axially into a machine or gear unit, because it makes that integration easier. Send us the machine drawing or the gearbox input details and we will confirm the mounting before quoting.

Yes. SIMOTICS models are inverter duty and run with Sinamics drives, and the same motors can be fed direct from the mains. For variable speed work we look at the speed range, the load at the bottom of that range and how often the drive starts, then confirm whether the standard cooling and insulation suit the duty.

IE2 meets a standard installation. On machines that run continuously, stepping up to IE3, IE4 or IE5 cuts energy use measurably across a year, and that is where the higher classes earn their place. We work it out against your running hours and load rather than name a class in the abstract.

Most models in the SIMOTICS range are designed and certified for S1, continuous duty, so they suit plant that runs all shift. Class F/B insulation adds thermal headroom on loaded drives with long cycles. Send the duty cycle and the ambient temperature with your enquiry and we will confirm the model against both.
