    3.1.4. Inverter selection The Inverter selection depends on at first on the available voltage and then on its rated power, nominal current and maximum electrical frequency have to be achieved by the drive and by the flux weakening ratio. Please refer to the drive technical documentation for any further information and to select the best motor and drive association.

  • Page 48: Motor Mounting

    GVM motors have been designed for an horizontal mounting (see §4.2). Considering the above schematics, GVM motors have to be supported on their rear side. For alternative mounting positions, please contact Parker. GVM motors have been designed for being assembled on gearboxes or hydraulic pumps and cannot support any axial / radial additional load on the shaft.

  • Page 49: Frame Recommendation

    It is recommended to change it once the predicted lifetime is reached. Please contact Parker in order to achieve this operation. Other limitations can come from the winding or the drive (cf: §3.1.4-Drive selection)

  • Page 50: Axial And Radial Load

    The bearing arrangement is made with 2 ball bearings (one on the shaft end + another on the rear). The rear bearing is blocked in axial translation and the front one is free in translation to avoid any stress from the shaft thermal expansion during the running. So, it is important not to block in translation the shaft expansion by any extra bearing or similar device.

    3.7. Thermal Protection – Positive Temperature Coefficient sensors Protection against thermal overloading of the motor is provided by three PTC thermistors and two linear temperature sensors equivalent to KTY84 (one is a redundant spare ; only one is connected) built into the stator winding as standard. Globally, the thermal sensors, due to their thermal inertia, are unable to follow very fast winding temperature variations.

    3.7.2. Temperature measurement with Linear Positive Temperature Coefficient sensors : Motor temperature can also be continuously measured by the drive using an LPTC thermal sensor (or equivalent) built in to the stator winding. LPTC sensors change their resistance according to an approximately linear characteristic. The required temperature limits for alarm and tripping can be set in the drive.
