Three-Phase Cast Iron Motor

SEVA-tec GmbH specialises in a wide range of challenges within the drive technology field with a focus on electric motors, frequency inverters, and gear motors. On this page, you will find a selection of AC motors in grey cast iron which are available in the following design sizes: 160, 180, 200, 225, 250, 280, 315, 355 and 400 with an electric capacity of 4kW, 5.5 kW, 7.5kW, 11kW, 15kW, 18.5 kW 22kW, 30kW, 37kW, 55kW, 75kW, 90kW, 110kW 160kW, 200kW, 250kW, 315kW up to 500kW. These motors are available in various rotation speeds, i.e. motors with pole numbers 2, 4, 6, and 8. You can of course purchase them as energy-saving motors in IE1, IE2, IE3, and IE4. In many cases, three-phase motors need to be designed to match the customer’s individual requirements. Our qualified staff, a large stock of motors and gearboxes, and our in-house final assembly make us the perfect partner for businesses that require external expertise across a large spectrum of issues. This can include a specific brake motor, circular saw motor, electric motor with a frequency inverter, pole switchable motors, special shaft, specific line voltage, or three-phase motors with different protection classes.

Asynchronous Motors – Protection Classes 

All motors and terminal boxes conform to protection class IP 55 in accordance with EN 60034-5. As required by this protection class, the cast iron motors are suitable for installation in dusty and humid environments. These motors must be protected from intensive sunlight when installed outdoors. For any electric motors with a shaft end located at the top of it, users should ensure that no water can enter the motor through the shaft. Upon request, the class of motor protection can be increased further for specific applications by introducing additional measures.  

Standstill Heating 

When three-phase motors are exposed to high-temperature fluctuations or extreme climatic conditions, there is a high risk of condensation formation. This poses a serious threat to the motor winding. Our optional, built-in standstill heater heats up the motor winding after switching it off and therefore prevents moisture precipitation inside the motor. During operation, the standstill heater should not be switched on.

Rotor Balancing 

The rotors of all motors are dynamically balanced according to DIN ISO 8821 with an inserted half feather key. Drive elements such as belt pulleys, couplings, and pump wheels must also be dynamically balanced with an inserted half key. Upon request, full key balancing is also possible.
