Electric motors iEM-II Series

BASIC ELECTRIC MOTOR MODULE iEM–II for synchronous power electric drives of high power

It is used in the following industries:

traction electric drives for small and medium vehicles

power servos for robotics and mechatronics

hoisting and transport equipment (winches)

shut-off valves electric drives

electric drives of pumps and ventilation

Art.: TSM01xxx

Key power characteristics of the iEM-II module: iEM-II:

• power: up to 900 kW (depending on the version and operating speed range)
• torque: up to 2’800 N x m
• specific torque: up to 22 N x m / kg

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

Key features:

• high torque
• modular design with hollow shaft allows for cascading of 2 or 3 modules on one shaft
• 3-phase stator
• the ability to control from standard frequency converters for synchronous motors
• low magnetic “sticking”
• efficient generator mode
• modern composite materials in the stator and rotor design

MAIN MODIFICATIONS

IEM-II Series High Torque Motor Modules are available in the following modifications:

iEM-II is air cooled standard with base performance. The priorities are low price and maximum import substitution.

iEM-IIL are air-cooled modules with improved or maximum specific performance relative to standard iEM-II modules. The priority is 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-IIw are liquid cooled modules with high specific characteristics. The priorities are low price and maximum import substitution while ensuring high specific characteristics.

iEM-IILw are forced liquid-cooled modules with improved or maximum specific characteristics relative to the iEM-IIw 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.
