The new Motor Drive System IE5/IE7

The motor design was tailored to the innovative i500-series frequency drive software. It uses the new SLSM algorithm (Sensorless Synchronous Motor). The exact rotor position is detected in the interaction between the motor and drive, which enables sensorless operation – without an expensive motor feedback system.​

Our new synchronous motors in IE5/IE7 are as easy to operate as an asynchronous motor and require less additional hardware. No wiring of an encoder is necessary. This reduces the installation effort and complexity right from the start. The high overload torque of 300% allows precise dimensioning and thus avoids expensive oversizing.​

Instead of just complying with the current specifications, we have gone one step further and developed synchronous motors in energy efficiency classes IE5 and IE7. This allows us to reduce motor losses by up to 60%. We achieve high energy efficiency even at partial load. In the long term, this further conserves resource and optimizes the CO₂ footprint.​ ​ ​

This function impresses machine operators in numerous applications: an overload torque of 300%. The permanent magnet synchronous motor accelerates from standstill to full load and gets bottle conveyors or box conveyors moving again without delay.​

The regenerative unit of the decentralized drive pays off in several ways. It enables braking energy to be fed back, thus saving energy costs, emissions and wiring work. ​ The control cabinet drives can also feed back energy via the DC network. ​

At the heart of the drive system is the new permanent magnet synchronous motor with a power range from ​0.25 to 11 kW. Gearboxes are available as helical, angular or bevel gearboxes. The i500 frequency drives in the cabinet, protec or motec versions and now the new i650 motec complete the portfolio.​
