Objective
The series of compact spindle motors from 
was developed to meet the OEM‘s requirements for the most versatile application options coupled with maximum compacted design while maintaining operational reliability, which in reference systems has already reached over 20,000operating hours without failure or maintenance.
Energy cost savings
Due to the electrophysical basic data of the PMSM technology used in the direct drive of the cutting tools, these spindle motors with their current service life and their 20 bis 25% better efficiency , taking into account real partial-load operation, have the following advantages compared to standard asynchronous motors with belt drive, a cost saving of around € 600,000 per motor.
Amortization in one year
This corresponds to around five times the purchase price. In other words, within each year of operation, our spindle drive recoups its entire purchase price.
Resume for OEM & end users
There are not many such efficient key points in a sawmill, and this proves that spindles driven by asynchronous standard motors and belts are not only a technology of the past, but also highly disadvantageous for their operation.

MCC4782 B-side
The MCC4782 spindle motor pair in use in a pre-cutting circular saw, viewed from the B-side, shows the core of the machine and the selection of the compacted machining element from the conveyor system.
MCC4782 80-450
Cutting big logs with a cutting height of 450 mm, for example, is no problem for the Megacut spindle motors. Eight or more side boards can be separated from the log (block or model) in one machine, producing 16 main products, for example. Hourly outputs of > 600 solid cubic meters are possible.

MCC4782 180-160
Cutting softwood at a speed of 200+ m/min is just right for the robust spindle motors. The slab sidings can be directly processed into sawdust. The speed control ensures the ideal cutting speed for every circular saw blade diameter.
Log turner
The disc turner rotor (only one moving part) enables left and right rotation as required and, if desired, in pairs for division into two feed lines in one. The mains backfeed eliminates any unproductive energy consumption. The gentle handling protects older wood from breakage.

Giant Feeder
Another unique solution for a feed mechanism for a disc chipper (e.g., 2500 mm disc diameter). Characterized by the fact that one side wall of the infeed is designed as a pusher and flying roller carrier. This eliminates the usual side opening slots that cause malfunctions.
Spiral Log Seperator
Invented, patented, and first manufactured by Häupl in 1987. Successfully in operation for 35 years. A success story that has developed into the standard equipment of the leading sawing industries over the last 15 years.
