Three-phase motors with permanently attached frequency converters - 1

Product Information: New from RGM Spotlights No screened motor cables Low power dissipation and voltage stress caused by internal cabling No problems with interference Space and cost-saving Can be retrotted onto existing drive motors The compact complete package: Three-phase motors with permanently attached frequency converters Three-phase motors with an output of up to 0.37 KW are now available. The elimination of external cables results in simplied connection, to name two of many advantages. Others are the lack of screened motor cables, low power dissipation and voltage stress caused by internal cabling, and unproblematic interference emission. Already existing drive motors can be easily retrotted onto existing drive motors. Furthermore, the complete package is space as well as cost saving and conform to Protection Category IP 55. The frequency converter operates at a cycle rate of approx. 10 kHz (switchable to 16 kHz). This enables outstanding motor smoothness and jolt-free operation, even at low motor speeds. The frequency converter is designed for two-quadrant-operation (drive operation in both rotation directions). Braking is possible up to the motor’s level of power dissipation, whereby the motor is operated at a level of overvoltage in breaking mode, drastically increasing the motor’s power dissipation. The machine is equipped with a thermal monitoring system which shuts down machine functions when an operating temperature of approx. 85 °C is exceeded.
