The synchronous servo/main spindle motors are perfectly matched to the SINAMICS drive system and to the SIMODRIVE 611 converter system. The high power/weight ratio of the synchronous servo/main spindle motors meets the main requirement for compact machine construction. The highlights of the motors are their:

• High overload capability
• High dynamic response
• High standstill torques

1FT7 servomotors

The 1FT7 motors are permanent magnet synchronous motors with highly compact dimensions. They meet the most stringent demands on precision, dynamics and speed setting range as well as on high degrees of protection and ruggedness. The motors are fitted with the latest encoder technology and are optimized for operation with our fully digital drive and control systems.
Natural, external or water-cooling are cooling types that can be selected. In the case of natural cooling, the developing thermal loss is drawn off via the surface area whereas an attached fan forces thermal loss away with external cooling. Maximum cooling – and, therefore, maximum performance – can be achieved with water-cooling.

1FK7 servomotors

1FK7 motors are permanent magnet excited synchronous motors which are available in the versions Compact, High Dynamic and High Inertia. The self-cooled motors are characterized by superior overload capability, ruggedness and compactness. The connection via rotatable connectors and preassembled cables ensures a flexible, fast and safe connection to the converter.
