SEW-EURODRIVE DR.J with LSPM AC Motor

• DR…J motors meet the requirements for efficiency classes IE2 to IE4
• Line start permanent magnet motor
  • Our LSPM technology is based on the addition of permanent magnets in the short-circuit cage of the AC asynchronous motors
  • In comparison to a DR.. series standard motor of the same power rating, you can select smaller sizes of the DR…J motors and achieve the same efficiency class
• Designed for operation on simple inverters with V/f control
• No rotor losses occur in operation
• Nine sizes in total (71S to 100L)
• Compact and robust design, low-maintenance
• Synchronous running of the motors with operating frequency
• Slip-free speed control without encoder feedback
• Group drive of several motors with synchronous speed on a frequency inverter
• Proven combination with MOVIMOT^®, the gearmotor with integrated frequency inverter
• High speed setting range with constant torque without forced cooling fan
• Many additional features of the modular motor system are available
• Can be combined with our gearmotors

The synchronous motors do not show any rotor losses in operation. They have an impressive degree of efficiency while maintaining a very compact design. In the same efficiency class, a DR..J motor with LSPM technology is two frame sizes smaller than a standard motor of the same power rating.
