The severe duty motors with their robust cast iron housing are the first choice for all major applications in normal industrial environments, as well as in harsh environments. They are very reliable, even under extreme conditions, versatile, extremely compact, and easy to handle. Very high efficiencies ensure economical and sustainable operation.
In addition to induction (asynchronous) motors for direct-on-line and converter operation, two different synchronous motor technologies are available. These need to be used always with a frequency converter (VSD).
Synchronous reluctance motor
For particularly energy-efficient operation, with keeping the standard power-shaft height assignment, the best choice is a VSD system with an Innomotics reluctance motor. The reluctance technology, without any rotor winding, ensures particularly high dynamic performance and high efficiencies even in the partial load range, as well as high process quality.
• Converter-optimized asynchronous motor (VSD10)
The investment-optimized system comprising a Innomotics SD VSD10 motor and a converter permits simple selection via a catalog or engineering tool, along with fast commissioning based on a data matrix code for predefined converter parameters. Optimum matching of the motors to operational conditions on the converter results in lower system losses and thus high energy efficiency.
