Having considerable experience in the field of design and production of crane electric motors with high performance, specialized electric motors manufactured by a Russian company Eldin The AMTK-F series with a short-circuited rotor are supplied to customers in various versions, which in turn are designed to complete the drives of tower, gantry, gantry, bridge and other cranes in construction, transport, metallurgy and other industries. The engine housings are made of cast iron of the SCH20 brand, have a class - A vibration degree, and are supplied with a nested key, at the same time, all engine rotors are dynamically balanced with a half-key.
Crane electric motors of the brand Eldin They are equipped with radial fans made of plastic or aluminum alloy, operating regardless of the direction of rotation. Depending on the customer's requirements, electric drives can be equipped with the following types of cooling: IC411 – (self–ventilation from a radial fan mounted on the motor shaft), or IC416 - (independent ventilation from an attached fan). At the same time, crane electric drives of the brand Eldin The AMTK-F series meet customer requirements in terms of application, high technical data, compliance with environmental standards and requirements, and at the same time high operational reliability. As a rule, all electric motors are supplied with a nested key, before operation, the drive elements mounted on the shaft (pulley, clutch) must be balanced taking into account the balancing of the motor rotor. As additional equipment, the customer is recommended to purchase incremental sensors (encoders) or resolvers.
