Synchronous electric motors with excitation from permanent magnets of the series TF from the company Oswald Elektromotoren GmbH They are characterized by outstanding torque performance at a low rotational speed, have a high output power density and low noise level. Excellent dynamics and controllability of work, low inertia. Their construction is based on a direct drive design with a very compact design, guaranteed accuracy and efficiency without backlash and loss of power indicators. In addition, these motors are not demanding in maintenance and have a long service life.
Liquid heat removal system through the cooling circuit, engine temperature is controlled by built-in 3PTC and 2KTY sensors in the basic version, other options on request. Mounting versions with hollow and solid shafts, mounting with a flange or on paws, as well as individual design solutions for specific customer needs are available. Various types of control sensors are available to choose from, optionally brake blocks and gearboxes can also be included in the package.
