8 Technical data
8.10 Connection of motor
CAUTION
The motor is for converter duty only.
CAUTION
The motor must be connected in DELTA (low voltage) to the converter.
The motor may not be started or operated with the mains supply, but may only be operated with a frequency converter.
All NORD frequency converters can operate the motors.
The motors can be operated with converter from other manufacturers. Several devices from other suppliers have been
successfully tested with the motors. The user is responsible for the success of commissioning. Also, the performance of the
motor, or the achievement of efficiencies which correspond to the classification depends on the converter and its function
and settings.
All motor data for IE4 motors are to be found in the table below.
Table 1. Motor data, IE4
CAUTION
The synchronous motor is for converter duty only as they are designed with permanent magnets in the rotor package.
The motor can only be operated by converters made for operating a IE4 motor.
