5.2.1 Motor connections requirements
The motor connections are the output from the IMD to the motor.
The requirements for the motor used with the IMD are listed in the following table:
Table 3
Motor requirements
Motor type
•
Synchronous 3 phases AC motor
•
Asynchronous 3 phases AC motor
•
DC motor
Insulation
•
Adequate for the voltage of the Mains input
•
Adequate for non-sinusoidal waveform of the IMD output
Resolver
Frequency: 10 kHz
Voltage: 7 V AC pp
No. of poles: 2 to 8
Built-in temperature sensor
Pt100, KTY 84 or PTC*, double insulated
Built-in brake
Voltage: 24 ± 10% V DC
Current: Maximum 5 A
Maximum cable length
10 m
* If PTC sensor is used the following IMD functions are not available:
•
High motor temperature warning
•
Actual motor temperature reading (only motor temperature too high error)
Info
Long
temperature sensor’s wires will impact the accuracy of the temperature
measurements.
Motor cable requirements:
The motor cable must be shielded. If any other cables (for example for the brake or the temperature
sensor) are inside the same cable they must be shielded separately.
The following figure illustrates an example of a cable containing the motor, brake, and temperature
sensor connections.
