Electric motors iEM-025 Series

NEW 2021 ELECTRIC MOTORS SERIES iEM-025
for high torque power servo drives

Applicable in the following industries:

power servo drives for robotics and mechatronics

power servos for medium UAVs

lifting and transport equipment (winches)

shut-off valve electric drives

Art.: TSM00xxx

Key power characteristics of the module iEM-025:

• power: up to 5 kW
• torque: up to 250 N x m
• specific torque, depending on version and type of heat sink: from 15 up to 39 N x m/kg
• heat dissipation options: without forced cooling; forced air or forced liquid cooling

Type: 3-phase synchronous multi-pole electric machine with independent excitation

Key features:

• record specific torque in its class
• high speed due to ultra-low rotor inertia
• small dimensions and weight
• 3-phase stator
• ability to control from standard frequency converters for synchronous motors
• small magnetic “sticking”
• small dimensions and weight
  
• modern composite materials in the construction of the stator and rotor

MAIN MODIFICATIONS

iEM-025 high-torque motor modules have the following modifications:

iEM-025 – standard air-cooled version with basic specifications. Priorities are low price and maximum import substitution.

iEM-025L – air-cooled modules with improved or maximum specific characteristics relative to standard iEM-025 modules. Priority – high or maximum specific characteristics in its class (specific torque or specific power). Limited import substitution for the Russian Federation, since imported materials and components are used to obtain the best specific characteristics.

iEM-025w are forced liquid-cooled modules with high specific characteristics. Priorities are low price and maximum import substitution while ensuring high specific characteristics.

iEM-025Lw are forced liquid-cooled modules with improved or maximum specific characteristics compared to iEM-025w modifications. The priority is to achieve the highest possible specific torque. Limited import substitution for the Russian Federation, since imported materials and components are used to obtain the best specific characteristics. As a rule, they are produced in limited quantities due to the high cost of products of this modification.
