Rotor manufactures standard and customized electric motors up to 8000kW, low, medium and high voltage, for industrial, marine, offshore and crane duty applications. Rotor provides innovative solutions to meet our customer’s needs in the toughest applications.
Ex II 2D and 3D Ex II according to EN 50014 and EN 50281-1-1. In case of dust-explosion-proof motors the level of protection is achieved by a certain degree of being dustproof in combination with a maximum surface temperature on the outside of the motor. In addition, sparking because of static electricity must be prevented. The maximum surface of the rotor nl® motors in both the Ex II 2D as well as the Ex II 3D version is 125 ° C. This is indicated on the nameplate as T = 125 ° C.
Electrical equipment, which is constructed according to protection type Ex-e, is not allowed to contain any components which can cause sparks or arcs under normal use that could lead to ignition of explosive gas. The explosive gas mixture is expected to be able to penetrate into the electrical equipment.
Crane & Offshore motors
Complex duty cycles and extreme conditions are the challenges in lifting and offshore applications.
The three-phase asynchronous motor or three-phase induction motor is a brushless asynchronous electric motor powered by a 3-phase AC system. This industrial electric motor is also known as AC motor or reverse synchronous motor.
The mechanical and electrical basic execution of the rotor nl® electric motors is adapted to marine and offshore applications. Given the often aggressive (saline) environment, the RN-series is almost completely available with cast iron motor homes and motor shields. Rotor produces electric motors for lower and upper deck use and, if necessary, with a fitted brake..
