Three-phase motors

IE2 covers a standard installation. On a machine that runs continuously, IE3, IE4 or IE5 cut the energy used across the year, which is where the higher classes pay for themselves. The three ranges we supply all reach IE5. Give us the running hours and the load and we will set the class against them instead of guessing.

Yes, and all three ranges are built for it. Siemens SIMOTICS motors are inverter duty and work with Sinamics drives. Most AC-Motoren models are inverter compatible, many with insulated bearings or reinforced windings. Tell us the drive and the speed range, because long spells at low speed affect what we recommend for cooling.

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

Siemens motors are IP55 as standard, which suits dust and moisture in most industrial settings, with IP56 or IP65 where the motor meets heavier dust or water. Damp, dust or a high ambient temperature can also push the build towards a different cooling arrangement. Describe the environment and we will specify against it.

The power and torque the machine needs, the supply voltage, the duty pattern, the mounting arrangement and the working environment. If the motor is a replacement, the old nameplate and the shaft dimensions save a lot of back and forth. With that we size the motor and quote within one working day, availability confirmed on the quote.
