Permanent magnet servo motor servo motor with 3 phase and grounded. Some standard servo motor also have reaction equipment, such as incremental encoder (With a hall sensor), absolute encoder or a resolver. Reaction to is part of the motor power cable, cable can also be separated from motor power cable. If the motor to connect to the servo drive, please close the drive power supply. Please follow the manufacturer's claims, in order to get the drive dissipation time of voltage. Disconnected from the drive motor phase line and grounding line. (Please pay attention to the cohesion, so that after the test from the beginning. )The standard line is bigger than response line. Do not need to disconnect the reaction from the drive line. Using the ohmmeter to see three phase motor (1 -2, 2 -3, 13)The resistance between. Different manufacturers for their motor phase using a different title (UVW XYZ 1 -2 -3,ABC), but for this test, it is arbitrary. These should be of the same resistance measurement of motor phase. Typical values less than 20 ohms. To view the resistance between the motor and the ground. These should measure the resistance of infinite. If the motor phase short circuit,Near zero resistance)Or grounding short circuit, the need to replace or repair the machine. This condition can lead to the servo drive is present. You can check the servo driver, if it is a new digital drive, will display the error log. Older drivers may have trouble lamp, the lamp may indicate motor trouble, over-current/bridge/I2T problem or other problems. Motor open phase? Usually, if the servo motor card in the machine, is a specific motor phase current will flow through than the other two phase, and in front of the other two phase short circuit. In the future, you can drop drive current, to avoid the motor over current. We almost all of the motor has a thermal switch or thermistors, disconnect, when the motor heat and help to avoid the motor over current. Check to see if the drive is cohesion; It is parker drive and the standard equipment of the cable. Drive also have monitoring flows of successive current and peak current to the motor, and has its limit within the scope of the rating of the motor. But, if the drive to reset the control power, and the motor has cooled enough to allow the degree of thermal kaifeng closed, may damage the maintenance function; Otherwise, it might damage the maintenance function. Use drive operates power or keep active state to avoid the over current. If rely on motor thermal switch to maintenance, will drive the peak current limiting current rating twice in a row for the motor. The motor rated current is based on the assumption that the environment temperature. If the environment temperature is very high, the demand is reduced current. All three motor phase short circuit? Servo motor all three phase short circuit is unusual. Under this situation, when the motor running, too much drive send on all the three-phase current. Check the drive motor equipment is correct and the current setting is in line with the rating. According to the motor rated current of the view of environmental temperature. If the environment temperature is very high, the demand is reduced rating of the motor and adjust the drive current Settings. Or demand in the motor (Fan or blower, pipes or larger radiator)Used on cooling.
