Torque motors
Torque motors are characterized by a very compact design in combination with a very high torque at low speed. A high power density in relation to the installation space and a low cogging torque are further points that a torque motor fulfills.
The torque motor essentially consists of a stator, which has a three-strand winding distributed symmetrically around the circumference, and a rotating part, the rotor, separated by an air gap. This is designed as a permanent magnet rotor and usually has very high polarity. Depending on the size, pole numbers of over 100 can be achieved. Torque motors are often integrated directly into the system as kits and can be designed as both internal and external rotors.
CEDS DURADRIVE torque motors have a space-saving design and high positioning accuracy. These motors are very often used instead of gearbox solutions and minimize wear and torsional backlash during positioning. Torque motors are a good choice wherever direct drives are possible, e.g. for rotary tables or rotating applications in defense technology. They can withstand harsh conditions and offer maximum precision. CEDS DURADRIVE torque kits are designed as a kit and can be fitted to the customer’s interface in a very compact and highly integrable manner.
CEDS DURADRIVE torque drives are individual solutions, both electrically and mechanically, which comply with customer specifications as well as legal regulations and are adapted to the climatic operating conditions. High requirements, such as particularly high nominal or peak torques in harsh climatic conditions, are not uncommon.
