21 Nm high torque DC electric motor type 3MTA-K

The high-torque 3MTA-К DC motor with a power of 3.29 kW (21Nm) is designed for feed drive mechanisms in metal-cutting machines and other actuating elements in modern automation systems, telemechanics, and measuring equipment.

Scopes of engines 3MTA-К:

1. Thyristor, transistor electric drives and feed drives of metal cutting machines;
2. Correction devices of hydraulic systems (to compensate for disturbing moments that cause precession of the gyroscope axis);
3. Stabilizing devices (position control system of various larger objects: antenna, sight, and others);
4. As tensioning devices to regulate or maintain unchanged the tension force of a wire, tape, chain);
5. As rotary electromagnets controlling dampers, valves, braking devices and so on.

The engine is designed in accordance with current standards and complies with the requirements and standards of IEC 72-1, IEC 34-1, IEC38, ISO2373.

The DC motor 3MTA-К is made with a built-in 4P tachogenerator (20V / 1000 min-1), an photoelectric raster converter and thermal protection. Thermal protection is implemented with the help of a posistor (temperature sensor) type RTT-250-120, which is installed in the engine.

In high-torque electric motors of type 3MTA-К of serial production, electrographic brushes of the EG2А grade 10x10x10/3x16x23 mm are used. (8 pcs.).

Characteristic features of the 3MTA-К engine:

• charged magnetic core;
• built-in thermal protection sensor;
• built-in encoder / pulcoder;
• degree of protection IP-44;
• built-in tachogenerator of direct current 4P (brush brand E43 4x5x10 mm. (4pcs.))
• high reliability and durability.
