Why using electric motors with integrated electronics?
First question: Why use Electric motors? - To replace mechanical link between f.e. seed drill and drive wheel. - Simple technology. - Reduce mechanical components (gears, chains, shafts,…). - Environmental friendly (replacement of hydraulics).
Second question: Why use electronics? - Electronic gearing (ratio can be set by digital parameter). - Extended motioncontrol (detection of locked seed drill). - Communication with Central Control Unit (CANopen/LINbus) - Protection of the drive f.e. against overload - …

That is why…
‐ Electronics are integrated inside motorhousing.
‐ Optimized protection against dust and humidity.
‐ Reduced cabling (motor/electronics)
‐ Decentralised motion control.
‐ Plug&Play solution
