Example : The application needs: - a rms torque of 6 Nm at the rms speed of 4000 rpm, - an acceleration torque of 25 Nm, - a maximal speed of 4000 rpm. Selection of motor: The selected motor is the type EY630EAN. The nominal speed is equals to 4000 rpm.
3.1.7. Current limitation at stall conditions (i.e. speed < 3 rpm) Recommended reduced current at speed < 3 rpm: reduced Warning: The current must be limited to the prescribed values. If the nominal torque has to be maintained at stop or low speed (< 3 rpm), imperatively limit the current to 70% of I (permanent current at low speed), in order to avoid an excessive overheating of the motor.
3.2.3. Electromagnetic losses Caution: Following data result from our best estimations but are indicative. They can vary from one motor to another and with temperature.

MOTOR PULSE WITHSTAND CHARACTERISTIC CURVES Curve EY motors Curve IEC 60034-25: <690V AC Curve IEC 60034-25: <500V AC Curve IEC 60034-17: <500V AC Voltage Pulse Rise Time (µs) Figure 1: Minimum Voltage withstands characteristics for motors insulations according to IEC standards. At the top are the typical capabilities for the EY motors. Note: The pulse rise times are defined in accordance with standards IEC/TS 60034-17 ed4.0 2006-05-09.
3.2.9. Voltage and current during operating EY motors present an ATEX certification and due to this certificate are subjected to strict rules regarding their use. One of such rules is the use of a servoamplifier that meets specific characteristics.These characteristics are valid for an ambient temperature comprised between -20°C and 40°C.
3.4. Motor mounting 3.4.1. Motor mounting By flange in any direction. 3.4.2. Installation of ATEX machines Keep in mind that EY motors are equipments with protect mode "nA" non sparking for hazardous area of gas and with protection by enclosure "tc" for hazardous area of dust ignition.
3.4.3. Frame recommendation Warning : The user has the entire responsibility to design and prepare the support, the coupling device, shaft line alignment, and shaft line balancing. Foundation must be even, sufficiently rigid and shall be dimensioned in order to avoid vibrations due to resonances.
3.5. Shaft Loads 3.5.1. Vibration resistance toshaft end Frequency domain :10 to 55 Hz according to EN 60068 -2-6 Vibration resistance to the shaft end : - radial 3 g - axial 1 g 3.5.2. Maximum load acceptable on the shaft Notice: Curves below are valid only for horizontal mounting and a life time L10 of 20 000h at constant speed in accordance with ISO281.
3.6. Cooling In compliance with the IEC 60034-1 standards: The ambient air temperature shall not be less than -20°C and more than 40°C. It is possible to use the motors in an higher ambient temperature between 40°C to 60°C but with an associated derating to the motor performances.
3.7. Thermal Protection The protection against thermal overloading of the motor is a PTC thermistors (as standard) built into the stator winding. The thermal sensor, due to their thermal inertia, are unable to follow very fast winding temperature variations. They acheive their thermal steady state after a few minutes.
3.8. Power Electrical Connections 3.8.1. Wires sizes In every country, you must respect all the local electrical installation regulations and standards. Not limiting example in France: NFC 15-100 or IEC 60364 as well in Europe. Cable selection depends on the cable construction, so refer to the cable technical documentation to choose wire sizes.
3.8.1. Earth connection to the rear cover Picture of the toothed washer which is placed between the rear cover and the lug and which prevents any rotation The earth cable has to be fixed to the motor with a tooth washer, a lug and a screw. This assembly holds the cable and secures the cable to prevent any rotation or movement in accordance with the requirements of standards IEC 60079-15 and EN 60079-15 cf.
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.

The brake should only be closed after the motor has come to a complete stop. The standard brake power supply is 24 Vcc DC ±...
4. COMMISSIONING, USE AND MAINTENANCE 4.1. Instructions for commissioning, use and maintenance 4.1.1. Equipment delivery All servomotors are strictly controlled during manufacturing, before shipping. While receiving it, it is necessary to verify motor condition and if it has not been damaged in transit.
4.1.3. Storage Before being mounted, the motor has to be stored in a dry place, without rapid or important temperature variations in order to avoid condensation. During storage, the ambient temperature must be kept between -20 and +60°C. If the torque motor has to be stored for a long time, verify that the shaft end, feet and the flange are coated with corrosion proof product.
4.2.3. Preparation Once the motor is installed, it must be possible to access the wiring, and read the manufacturer’s plate. Air must be able to circulate around the motor for cooling purposes. Clean the shaft using a cloth soaked in white spirit or alcohol. Pay attention that the cleaning solution does not get on to the bearings.
Warning : a misalignment of the coupling device makes stress and load on the motor shaft depending the rigidity of the installation. The variations of the temperature makes stress and load due to the dilatation. These loads (axials and radiale) do not exceed the load written (§...
