DR.. series:
DR...J design (LSPM* technology)
* Line Start Permanent Magnet
Features
–
The
DR..J
synchronous motor design (LSPM technology) is integrated in the DR.. series
modular motor system and is designed in the sizes 71S to 100L. The technology is based
on adding permanent magnets below the squirrel cage of AC asynchronous motors
–
No rotor losses
occur during operation: high efficiency from IE2 to IE4
–
Compared to series motors with the same power range, the same energy efficiency class
is achieved with a smaller size of the DR…J motors (LSPM technology)
–
Compact and robust design
–
Synchronous running of the motors with operating frequency
–
Slip-free speed control without encoder feedback
–
DR.. J LSPM motors can be operated with the frequency inverters MOVITRAC
®
LTE-B and
MOVITRAC
®
LTP-B, MOVITRAC
®
B, MOVIFIT
®
FC and MOVIMOT

D
–
Can be used as individual or group drive with a frequency inverter
–
Many additional features of the modular motor system are available
–
Can be combined with the 7-series of the modular gear unit system from SEW-EURODRIVE
–
Constant torque CT in the speed setting range without forced cooling fan
