2. PRODUCT DESCRIPTION 2.1. Quick URL All informations and datas are avaible on : http://www.parker.com/eme/tk 2.2. Overview The TK frameless servomotor are the active parts of a servo motor: a rotor and a stator. The TK series can not be used alone and must integrated into a complete system to provide a complete torque motor. The design, the construction, the certification and the tests are the responsibility of the integrator. TK Torque Motors Series in kit version from PARKER are innovative direct drive solutions designed for industrial applications requiring high torque at low speed. TK Torque...

2.3. Motor description PARKER Torque Motors have been especially designed to replace traditional motor + gearbox sets or traditional motor + timing belt on machine tool table, winders, crushers, mixers, and more generally in all application segments requiring kit torque motors with a power up to 400kW.

3. TECHNICAL DATAS 3.1. Motor selection 3.1.1. Altitude derating From 0 to1000 m : no derating From 1000 to 4000 m : torque derating of 5% for each step of 1000 m for TKW From 1000 to 4000 m : torque derating of 10% for each step of 1000 m for TKA 3.1.2. Temperature derating 3.1.2.1. Natural cooled motor The maximal temperature for natural cooling is 40°C. But, it is possible to increase a little bit the ambient temperature above 40°C, with a torque reduction. The following formula gives an indicative about the torque derating at low speed. But in any case refer to PARKER technical department...

3.1.2.2. Water cooled motor Typical values are given with a water inlet temperature of 25°C and a temperature gradient Inlet-Outlet of 10°C. These references lead to a winding overheating of 95°C corresponding to a winding temperature of 120°C. Recommendations regarding condensation issues are given at § 3.5 It is possible to increase a little bit the Inlet temperature up to 45°C, but the torque must be reduced. The following curves give an indicative of the derating versus the speed for different temperature. Derating coefficient with inlet water temperature Derating curve vs speed for TKW13x...

Thermal equivalent torque (rms torque) The selection of the right motor can be made through the calculation of the rms torque Mrms (i.e. root mean squared torque) (sometimes called equivalent torque). This calculation does not take into account the thermal time constant. It can be used only if the overload time is much shorter than the copper thermal time constant. The rms torque Mrms reflects the heating of the motor during its duty cycle. Let us consider: - the period of the cycle T [s], - the successively samples of movements i characterized each ones by the maximal torque Mi [Nm] reached...
