Crane Electric Motors MTF, MTH, DMTF, AMTF, MTKF

Buy Crane Electric Motors: Reliable Drive for Harsh Environments

Crane electric motors are heavy-duty specialized machines engineered to operate in intermittent periodic duty cycles (S3) involving frequent starts, reversals, and electrical braking. They are widely utilized to power the drive mechanisms of tower, gantry, overhead traveling, and portal cranes, as well as other material handling equipment.

Our catalog features a comprehensive spectrum of modifications, allowing you to accurately select and buy a crane electric motor matching your specific operational requirements.

Crane Motor Product Range: Key Series

For ease of selection, all models are classified into two major categories based on their rotor design:

1. Slip Ring (Wound) Rotor Motors (For smooth starting and speed regulation)

These motors deliver high starting torque paired with relatively low starting currents. They are ideal for speed-controlled mechanisms and heavy-duty starting conditions.

• Classic & Upgraded Series: MTF, MTH, MTI.

• High-Power & Heavy-Duty Series: 4MTM, 4MTH.

• Specialized & Modern Series: DMTF, DMTH, AMTF, AMTH.

2. Squirrel Cage Rotor Motors (For simple and robust solutions)

Characterized by a simple design, minimal maintenance needs, and exceptional reliability. They are frequently used in drive systems controlled by variable frequency drives (VFDs).

• Baseline Series: MTKF, MTKH, MTKI.

• Modernized Product Lines: 4MTKM.

• Protected & Specialized Configurations: DMTKF, DMTKN, AMTKF, AMTKH.

Technical Characteristics & Operating Conditions

The MTF (MTKF) and MTH (MTKH) series crane motors are manufactured in various climatic configurations and are engineered to withstand high vibration levels, dusty environments, and broad temperature ranges.

Important: Letter designations in the model code (e.g., F, H) indicate the thermal insulation class of the windings. Class H (up to 180°C) provides superior thermal overload resistance compared to Class F (up to 155°C), which is crucial for metallurgical plants and hot-shop environments.
