2 ,LTD. 145 SPEED -Torque Characteristics of SPEED CONTROL SystemsThe SPEED -torque characteristics line of all AC SPEED CONTROL motors characteristics is shown in the figure set SPEED changes slightly according to the change in load torque. Safe Operation Line and Permissible Torque When Using a GearheadInput power to the SPEED CONTROL motor depends on the load and SPEED . The greater the load, and the lower the SPEED , thegreater an increase in motor the SPEED -torque characteristics graph, the line is referred to as the safeoperation line, while the area below the line is called the continuous operation safe operation line, measured according to motor temperature, indicates its operational limit for continuous usage withthe temperature.

3 Whether the motor can be operated at a specific torque and SPEED is determined by measuring thetemperature of the motor case. In general, if the motor 's case temperature is below 90 (194 ), continuous operation ispossible, considering the insulation class of motor coil winding. But the motor life could be extended with lower motortemperature. So it is recommended that the motor be used under conditions that keep the motor temperature has two kinds of cooling fan ; General fna (F type) and Powerful fan (F2 type). F fan is attached in motor shaft and itsspeed depends on the motor shaft SPEED . So in slow SPEED of motor , there is very weak cooling effect.

4 In the applicationwhere motor SPEED should be changed from low SPEED (below 1,000 rpm) to hight SPEED like SPEED CONTROL motor , F2 fan isneeded so that cooling effect keep constantly regardless of the motor case of SPEED CONTROL motor and inverter motor , DKM is employing F2 type fan into them basically. ; In special applicationor by user s request F type fan can be employed in SPEED CONTROL motor and inverter motor . And please be advised that in all motors, F2 fan can be attached by user s CONTROL Technical Reference SPEED CONTROL Methods of SPEED CONTROL Systems By a potentiometer, the SPEED setting voltage is supplied.

5 The motors SPEED is sensed and the SPEED signal voltage is supplied. The difference between the SPEED setting voltage and SPEED signal voltage is supplied. A voltage determined by the output from the capacitor is supplied to the motor so that it will reach the set SPEED . 145-1 DKM CO., FX1000A series combines a CONTROL unit and AC SPEED Controlmotor. Connection between the motor and CONTROL Unit is simplifiedby an easy-to-use connector. Digital Type SPEED CONTROL MotorFX1000A CONTROL SYSTEM Features Easy Connection CONTROL units combine the CONTROL pack, potentiometer and capacitor into one device. Operation is possible just by connectingthe CONTROL unit into power supply after connecting the motor and CONTROL unit together using the connector.

6 Easy Operation The SPEED can be set easily with the potentiometer on the front panel of the CONTROL unit. DIGIRAL DISPLAY The motor SPEED can see directly on the front panel of display of the CONTROL unit.
