Servomotors 1FT7

The compact synchronous motors for high-performance applications

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.

1FT7 synchronous motors - typical areas of application

High-performance Motion Control and positioning applications in production machines such as packaging machines, textile machines, foil drawing machines, printing machines as well as in conveyor technology and in manipulating devices. Feed drives in high-performance machine tools.

1FT7 Compact are, due to their low torque ripple, predestined for use in machine tools where high surface quality and optimum machining results matter. Thanks to their compact design, they are ideal for use in limited installation space.

1FT7 High Dynamic have a very low rotor inertia to achieve extremely high dynamics and shortest cycle times. The motors 1FT7 High Dynamic are available in cooling types for external cooling and water-cooling ensuring high continuous power capability.
