Dongqi overhead crane motor type for your need

Dongqi provide our customers the best overhead crane motor.In general,we use homemade crane motor.If our customers need European crane motor,we can also provide it for you.

DOMESTIC CRANE REBUILT MOTORS:  Performing like new at a fraction of the cost.

• Here are just a few of the competitive advantages offered by our in-house motor design and manufacturing capabilities:
• Proprietary Wire - Heavy gauge fiberglass over enamel wire for improved varnish retention to withstand mechanical forces and provide higher heat resistance.
• High Efficiency Design - OE diamond shaped coils offer more efficient end turns than standard round-end turns (mush wound).
• Maximum Durability - Class H insulation increases temperature tolerances.
• Core Loss Testing – Measures and eliminates core losses that lead to motor and higher operating temperatures.
• Craftsmanship - Rotor connectors are copper banded, TIG welded, taped and covered for optimal heat resistance.
• Quality Processes - Rotors and stators are dipped multiple times without solvent according to OE specs, including VPI for larger frame sizes.

Siemens crane motors are often exposed to extreme weather conditions – as well as being subject to high operational requirements. They have to withstand high humidity, salty air and high wind speeds while ensuring a high overload capacity and a wide speed control range. However, topmost priority is that the motors function reliably.

Customer benefits

Increased efficiency 

The use of active parts for high efficiency in DOL/variable speed operation, this motor also helps to reduce energy usage. For ambient temperatures up to 50 °C, optionally also higher – Protected against humidity up to 100% and salty atmosphere.

More power 

Torque reserves for high surge loads and an overload capacity up to 230% – used as accelerating drives, our crane motors master any situation. The high power density facilitates compact dimensions.

More flexibility 

Using a generously dimensioned terminal box, corrosion protection inside the motor and optionally available rugged mounting feet and flange manufactured from a torsionally stiff spheroidal graphite iron – our crane motors can cope with any task.

Typical applications

The robust cast iron motors have been specifically designed for rugged operation under tough crane operating conditions – in salt-laden atmospheres, high air humidity and high wind conditions. Typical applications in harbour environments include rubber-tired gantries, rail-mounted gantries, automatic stacking cranes etc.
