Motors boost performance but cut size
Stator currents are lower, generating lower losses due to low current demand, which in turn reduces temperatures in the windings and bearings.
Lafert has released a motor that reduces running costs and the space required for installation Savings on operating costs can amount to more than 80% while the motor's output enables significant frame size reductions plus weight savings

New range of aluminium induction motors introduced
Available in frame sizes 63-180 and powers 0.12-30kW, the new AEG Electric Motors aluminium induction motor range has improved efficiencies and now complies with the CEMEP Eff 1 category
Debut at Drives and Controls
AEG Lafert Electric Motors will be exhibiting its range of induction motors for the first time at the Drives and Controls Show at the UK NEC.
The High Performance (HP) motor combines brushless permanent magnet motors and conventional AC induction motors.
Combining these technologies provides substantial efficiency advantages over conventional AC induction motors.
Stator currents are lower, generating lower losses due to low current demand, which in turn reduces temperatures in the windings and bearings.
These low-temperature rises can go on to eliminate the need for a cooling fan and its related losses.
Minimised heat allows higher running speeds or extended bearing life.
The enhanced performance of the HP motor permits Lafert to offer smaller frame size solutions and weight savings of around 50%.
All these features combine to enable engineers to achieve compact, efficient drive solutions, particularly for applications involving pumps, fans and compressors.
The HP motors are available for both single and three-phase supply versions, with ratings of 0.75 to 2.2kW, 200 - 240V, 50/60Hz and 0.75 - 22kW, 380 to 480V and 50/60Hz, respectively.
The HP motor can be used with a standard servo drive when fitted with an appropriate transducer, but should ideally be used with a sensorless drive developed by Lafert Drives to maximise the motor's performance in the specific application.
