High-torque DC electric motors of the MT series (models 2MTA, 3MTA, 4MTA, 4MTB, 5MT) are specifically engineered for actuators and feed drives in modern metal-cutting machine tools, including high-precision CNC machinery. With a torque range spanning from 13 to 47 Nm, these motors ensure smooth and precise positioning of the machine's working components.
Key Advantages and Design Features:
-
High Overload Capacity: The permanent magnet excitation system ensures stable performance and outstanding resistance to peak loads in both static and dynamic (transient) operation modes.
-
Reliability and Protection: All MT series motors feature a built-in tachogenerator for speed monitoring and a thermal sensor for overheat protection. The enclosure design fully complies with strict international IEC 34-5 and IEC 34-7 standards.
-
Flexible Modular Configurations: Depending on your technical requirements, modifications can be supplied with a built-in zero-backlash electromagnetic brake, a contactless resolver (RB-2 type with 1:2.5 or 1:5 multiplier), or a photoelectric pulse encoder.
The MT motor lineup is a time-tested solution for retrofitting and repairing machine tools, delivering exceptional durability and minimal backlash under heavy-duty metalworking conditions.
