Grundfos SPE Pumps – Robust Motor Design

By Grundfos

Discover how submersible motors, essential for deep well water supply, irrigation, and pressure boosting, rely on robust insulation systems to handle peak voltage levels during operation. When driven by a Variable Frequency Drive (VFD), long cables can elevate these peak voltages, posing challenges for motor insulation. Learn about the two main stator types—wet-wound and potted—used in submersible motors, and how sine wave filters protect the motor insulation system from transient voltages caused by VFDs. Understand the critical role of sine wave filters in reducing detrimental voltage spikes and electromagnetic noise. Motors not designed for VFD operation without a sine wave filter are prone to insulation system failures. However, the Grundfos MS6000P motor is engineered to operate without a sine wave filter, reducing system cost and complexity. Download now to delve into the advanced design and application of submersible motors with VFDs and sine wave filters.
