Rotor
The rotor has a squirrel cage rotor manufactured out of die-cast aluminum or a brazed copper
rotor. The rotor is dynamically balanced. The balance condition is stated on the shaft end face
or rating plate.
Bearings
The motors are equipped with grease-lubricated roller bearings.
● The bearings of the standard version motors (up to size 280) are permanently lubricated.
● The bearings of motors from size 315 upwards have a relubrication facility and automatic
Terminal boxes
In the motor terminal box, additional connecting terminals are available if required for
monitoring equipment. For larger machines, an additional terminal box can be optionally
mounted. You can see the number of available terminals in the circuit diagrams.
Paint finish
The machine is painted according to the instructions in your order.
Monitoring equipment
Monitoring equipment is provided corresponding to what has been ordered. KTY83 and KTY84
semiconductor sensors are electrostatic sensitive devices (ESD). These elements can be
damaged by electrostatic discharge. Observe the ESD protective measures (Page 17).
Risk of explosion during operation due to too high surface temperature
This can result in death, serious injury, or material damage.
• Prevent the maximum surface temperature from being exceeded by maintaining the
specified operating conditions.
• Monitor the coil temperature. Use the temperature sensor that is built into the stator winding
for this as specified on the rating plate or extra rating plate.
Anti-condensation heating
The machine can be fitted with anti-condensation heating. The connection data is listed on an
additional plate on the machine.
