TF TORQUE MOTORS: HIGH TORQUE - LOW SPEED MOTORS

Product catalog summary

General Description:
The document describes the Series TF torque motors, which are water-cooled PM synchronous motors. These motors feature a ring-shaped geometry with a hollow shaft and rare-earth magnets, providing direct drive with high torque at low speeds. They are compact, robust, low-maintenance, and have excellent control properties, comparable to synchron servomotors. Bearings can be part of the motor or the customer's machine, with optional axial self-aligning roller bearings.

Specifications:
- Rated voltage varies between 330V and 360V depending on stator windings.
- Rated speed and power are customizable.
- Field weakening range is 1.5 to 2 times the rated speed with a suitable frequency inverter.
- Thermal class F according to DIN EN 60034 / VDE 0530, with a winding temperature of 105 K above ambient.
- Enclosure protection ranges from IP23 to IP54.

Cooling Systems:
The motors are liquid-cooled, with a standard coolant inlet temperature of 25°C. Higher temperatures require power reduction. The cooling system includes a copper coolant circuit, and the flow rate, water pressure, and pipe fittings must adhere to specified standards. Anti-corrosion protection is not required, but filtering of particles larger than 100μm is necessary.

Design and Dimensions:
Mechanical dimensions vary, with water connections ranging from 1/2 inch to 1 inch depending on the model. The number of fastening bolts may vary, and enhanced housing is available upon request.

Feedback Systems and Additional Features:
Feedback systems for rotor position and motor speed are available, including hollow shaft encoders and excentric mounting with belts. Brakes and gears can also be mounted upon request.

Standards and Compliance:
The motors comply with DIN EN 60034 / VDE 0530 standards, with specific requirements for voltage peaks and pulse rise times. Temperature monitoring is standard with 3PTC+2KTY sensors, with other options available.
