FAQ

What does the “-Z” suffix in the model number 1LE1003-1DB43-4AC4-Z signify?

The “-Z” suffix in a Siemens MLFB (model number) indicates that the motor includes one or more custom options or modifications beyond the standard configuration. These could relate to special paint, shaft dimensions, or specific electrical characteristics.

Can this motor be operated with a variable frequency drive (VFD)?

Yes, Siemens SIMOTICS GP motors like this one are generally suitable for operation with a VFD. However, it is crucial to ensure the VFD settings are correctly configured for the motor’s specifications to prevent overheating and ensure optimal performance, especially at low speeds.

What are the specified bearings (DE/NE 6209-2ZC3), and what maintenance do they require?

The motor uses 6209-2ZC3 bearings on both the Drive End (DE) and Non-Drive End (NE). These are deep groove ball bearings with metal shields on both sides (2Z) and C3 internal clearance. As they are shielded and pre-lubricated (“lubricated for life”), they typically do not require re-greasing under normal operating conditions.
