1. INTRODUCTION 1.1. Purpose and intended audience This manual contains information that must be observed to select, install, operate and maintain PARKER HKW high speed motors in kit. The design, tests, certification, commissioning, operation and maintenance of the equipment should be carried out by qualified personnel. A qualified person is someone who is technically competent and familiar with all safety information and established safety practices; with the installation process, operation and maintenance of this equipment; and with all the hazards involved. Reading and understanding the...

General Safety Rules Generality DANGER: The installation, commission and operation must be performed by qualified personnel, in conjunction with this documentation. The qualified personnel must know the safety (C18510 authorization, standard VDE 0105 or IEC 0364) and local regulations. They must be authorized to install, commission and operate in accordance with established practices and standards. Electrical hazard Servo drives may contain non-insulated live AC or DC components. Respect the drives commissioning manual. Users are advised to guard against access to live parts before...

2. PRODUCT DESCRIPTION 2.1. Quick URL All informations and datas are avaible on : www.parker.com/eme/hkw 2.2. Overview The HKW frameless servomotor are the active parts of a servo motor: a rotor and a stator. The HKW series can not be used alone and must integrated into a complete system to provide a complete servomotor. The design, the construction, the certification and the tests are the responsibility of the integrator. HKW series is high-speed motor in kit version from PARKER. HKW are innovating solutions through direct drive, specifically conceived for industrial applications where...

2.3. Motor description and Applications The HKW motors are delivered as individual components: a rotor with or without hub and a stator with or without housing. PARKER can provide position sensor (2 poles resolver giving an absolute position on one turn) as an option. Housing O-ring seal groove Stator (lamination stack + windings) Hub Rotor (lamination stack + magnets 2 rings to balance rotor Power cable Temperature sensor cable Without hub and housing version With hub and housing version Many windings are available to get the wished torque and speed characteristics for power up to 80KW...

These components are typically assembled according to Figure 1 to make a complete motor spindle unit. The stator is water cooled to allow a higher torque density and a lower stator temperature rise. The motor is designed to have a large shaft diameter to increase the mechanical rigidity. 1 Stator housing 2 Rotor 3 Winding 5 Resolver’s rotor 4 O-Ring 6 Resolver’s stator Figure 1 : Typical HKW motor assembly The HKW motors have been successfully used in all high speed machine and specially in machine tool applications in place of the traditional induction motors. For the end user the main...

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 3.1.2. Temperature derating 3.1.2.1. 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 90°C corresponding to a winding temperature of 115°C. Recommendations regarding condensation issues are given at § 3.5 It is possible to increase a little bit the Inlet temperature up to 40°C, but the torque must be...

3.1.3. 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]...
