Degrees of protection for motors

All motors and connexion boxes are designed to match IP 55 in accordance with EN 60034-5.As required by this standard, the AC motors are suitable for installation in a dusty and humid environment. When installed outdoors, the motors must be protected from intense exposition to the sun. For electric motors where the shaft end is located at the top, the user has to make sure that no water enters the motors via the shaft. In specific cases of application, we can on request increase the degree of protection specified on the motor nameplate by taking additional measures.

Heating during stoppage

On three-phase motors which are exposed to great temperature variations or extreme climatic conditions, condensate formation or condensation poses hazards to the motor winding. An optional incorporated heating during stoppage can heat the motor winding after the motor is switched off and prevent moisture from depositing inside the motor.The heating during stoppage should be switched on when the motor is operating. 

Rotor balancing

On all motors, the rotors, with ½ shaft key fitted, are dynamically balanced in accordance with DIN ISO 8821. Drive elements such as belt pulleys, clutches and pump wheels must also be dynamically balanced with ½ shaft key fitted. Care must be taken that the length of the hub and the length of the keyway coincide to prevent any additional residual unbalance. Also full-key balancing is possible upon specific request.

Running truth

All motors are balanced and made with tight tolerances on running truth so that the vibration characteristics of the motors correspond with the vibration intensity level A as per DIN EN 60034-14. If specific requirements are placed on running truth, motors can be supplied in low-vibration design.
