The SKAddl direct drive motors offer an unmatched choice of construction formats making it easy for the customer to select the motor perfect for the application.
By implementing a modular approach to the motor construction it can be tailored to your exact needs, whether you are a large scale OEM or a small special purpose machine builder.
The SKAddl direct drive motors are particularly suited to applications where high-speed motion with high-positioning accuracy are demanded. The direct drive technology, besides eliminating backlash and mechanical elasticity in the drive transmission, drastically lowers maintenance costs while achieving appreciable energy savings through improved overall efficiency.

 |
|
SKA DDL (Direct Drive Linear) frameless, comprising coil and magnet track. OEM product. |
SKA DDL custom mount with integrated guides, cable management and encoder. | SKA DDL power pack, comprising the linear motor, guides and feedback devise, contained in an extruded aluminium housing (currently only on 55HX and 55HS). |
Featuring an excellent nominal and peak torque capacity plus high acceleration and deceleration values, the SKAddl direct drive servomotors achieve efficiencies and precision positioning that are difficult to obtain with conventional systems.
Natural evolution of direct coupling between the motor and driven load, the conventional components of the kinematic chain have been totally eliminated from these servomotors.
Features
Iron-core synchronous motor
Moving coil insulation class F
Transducers: sin-cos encoder, TTL (optical and magnetic)
Two mounting solutions: frameless and stand-alone version
Stand-alone version supplied as complete plug and play system. Temperature sensor, linear guides, flexible encoder, cables and cables carrier are included in the motor.
