 | Low motor temperature
Due to a unique thin rotor can and close rotor to stator tolerance in the MS motors,
internal rotor losses are minimized. Large cooling surfaces and internal fill fluid
circulation provides efficient heat transfer resulting in cooler operating temperatures. Lower motor temperature means longer lifetimes. | Voltage tolerance
To assure adequate voltage is applied to the motor, Grundfos recommends a maximum of 5% cable loss. Supplying the correct voltage to the motor ensures proper starting torque and cooler operating temperatures
are achieved. |
