Electric Motors with integrated electronics for the

Agriculture market

Example : Seeding machines

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 - …

Third question: Why integrated electronics?

That is why…

‐ Electronics are integrated inside motorhousing.

‐ Optimized protection against dust and humidity.

‐ Reduced cabling (motor/electronics)

‐ Decentralised motion control.

‐ Plug&Play solution

Features of the integrated electronics Hardware level:

• Communication with CAN and CANopen Interface.

• Up to 8 I/O channels for analog and digital out- / inputs.

• Integrated incremental or absolute encoder.

• Speed and Position control.

• IP67 option.

• Sinus Wave Commutation or PWM.

• Angle Resolution up to 360 Pulse/motorrevolution.

Software level:

• Implementation of complex customer driven tasks

• Auxiliary tasks (f.e. Read external sensor, control external devices,…)
