SIMOTICS T-1FW6 built-in torque motors with jacket cooling (left), natural cooling (middle) and with integrated cooling (right)

SIMOTICS T-1FW6 built-in torque motors are liquid-cooled or naturally cooled, multi-pole permanent magnet AC synchronous motors with hollow-shaft rotor. The motors are supplied as built-in components that are held together in the delivered state by transport locks. For a complete drive unit, an additional bearing and shaft encoder are required.

Each frame size is available in different axis lengths. Most stators and rotors are equipped with flanges at each end with centering surfaces and threaded holes for installation in the machine.

Please note that when SIMOTICS T-1FW6 direct motors (torque motors) are used in fork heads for machine tools or robots, a license for US patent US5584621 and the associated international patent protection may be required. Please observe the national and international licensing conditions when using direct motors so that no infringements of industrial property rights occur.

Дизайн

The SIMOTICS T-1FW6 built-in torque motor comprises the following components:

Stator

Stator design with a 3-phase AC winding. Generally, the stator is designed for operation with liquid cooling.

Rotor

Cylindrical hollow shaft made of steel with permanent magnets fixed to the circumference.

If the main cooler and precision cooler are used together in a cooling unit, a cooling connection adapter (accessory) can be ordered separately for simpler connection.

Cooler types

The design of the cooling system is dependent on the size (external diameter) of the motor.

Motors with natural cooling

The motors with natural cooling have the same dimensions as the water-cooled motors in frame sizes 1FW6050 and 1FW6060. They offer a lower continuous torque due to their type of cooling. The motors with natural cooling are used in applications for which liquid cooling is not desired or necessary. The type of cooling can be easily changed since the motors are compatible in terms of mechanical interfaces as well as their dimensions.

Motor components of sizes 1FW6053 and 1FW6063 with natural cooling (rotor and stator)

Motors with integrated single-circuit cooling

These motors have a ready-to-connect, integrated single-circuit cooling system; they are compact and therefore suitable for easy integration in a machine.

Motors with jacket cooling

The coolant inlet/return flow circuitmust be provided by the machine manufacturer in the surrounding construction.

Motor components of sizes 1FW6090 to 1FW6150 with jacket cooling (rotor and stator)

Motors with integrated dual-circuit cooling

These motors feature a ready-to-connect, integrated dual-circuit cooling system and are therefore thermally insulated against the mechanical axis construction to a considerable extent.

Интеграция

The 1FW6 motors which must be fed from the SINAMICS S120 drive system are designed for operation on a 600 V DC-link voltage level and require a sinusoidal current.

The cable connection is brought out of the front face of the stator and the free cable end must be connected to a terminal box provided by the machine manufacturer. The length of the power and signal cables from the motor to the drive system must not exceed 50 m (164 ft).

Absolute measuring systems with DRIVE-CLiQ

Measuring systems with integrated DRIVE-CLiQ interface are available from different manufacuters. The encoders can be used as motor feedback system.

The current overview of manufacturers and available measuring systems can be found at :

In addition, absolute measuring systems with EnDat 2.1 and incremental measuring systems with 1 V_pp can be used.

Особенности

• No elasticity in the drive train
• High availability, since there are no gear components subject to wear in the drive train
• High torque, compact design and low construction volume
• Low moment of inertia
• Direct coupling to the machine using flanges
