At high speed, the calculation is more complex, and the derating is much more important. Please refer to PARKER to know the precise data of torque derating according to ambient temperature at high speed for a specific kit. 11 - PVD 3674_GB_K Series_CE-November 2016.Docx...
3.1.3. Thermal equivalent torque (rms torque) The selection of the right kit can be made through the calculation of the rms torque (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 motor adapted to the duty cycle has to provide the rms torque M at the rms speed(*) without extra heating. This means that the permanent torque M available at the average speed presents a sufficient margin regarding the rms torque M rms.

Voltage and maximum speed: The bus voltage and maximum speed will approximately determine the required voltage constant (Ke). Note that in many windings, the max mechanical speed limits the top speed. Example: : K178050-EY Power supply : 240Vac Bus voltage : Ubus=324 Vdc Voltage drop from drive : 7%...

Rotor Except for the smaller motors (K032 and K044), the ID of the rotor is usually larger than the shaft diameter. An adapter sleeve (steel or aluminum) allows the rotor to be mounted to the shaft. The rotor/sleeve assembly must be positioned on the shaft such that the magnets are located in line with the stator assembly laminations.
Page 41
Activator #7074 Loctite #609 Final Assembly: Rotor magnets to be in line with stator laminations and concentric to stator lamination I.D. within 0.127 mm MAX. Caution : Rotor assembly magnets are powerful and fragile! Do not place near magnetically sensitive material. Do not place near other ferromagnetic materials such as iron, steel and nickel alloys.

Example: Hold the rotor / shaft / product assembly in a machine tool vise on the base of an arbor press. Fasten the stator assembly to the vertical moving member of the arbor press, away from the stator. Slowly lower the stator assembly around the rotor / shaft / product assembly. Tighten all fasteners to complete assembly.
3.4.5. Design Compliance The integrator is responsible for compliance with directives, regulations and standards.

For motors windings which present low inductance values or low resistance values, the own cable inductance, respectively own resistance, in case of large cable length can greatly reduce the maximum speed of the motor. Please contact PARKER for further information.
3.7. Feedback system An angular position sensor is often used to run the motor and it depends on the drive functionalities and application. A drive with a sensorless mode needn’t a feedback system. A classic position sensor is an encoder, a commutation Hall effect ensor and resolver. Attention: Do not mix feedback wires with motor wires to avoid EMI (electromagnetic interference).
3.7.2. Resolver 3.7.2.1. Overview A resolver is an angular position sensor. It is used to determine rotor position. Its signals are processed by the drive in order to control the stator currents, the speed and the position. The resolver is a high precision device and must be wired and mounted with care. 3.7.2.2.
