Standard basic models of servo motors sEM-07 and special versions sEM-07L are designed for use in high-precision power servo drives of CNC machines, machining centers, 3D printers and other industrial automation systems, robotics and mechatronics.
Thanks to their impressive torque with ultra-small weight and dimensions, servo motors of the sEM-07 series allow you to partially or completely eliminate the mechanical gearbox as part of the power servo drive!
sEM-07 servomotors can be used without forced air cooling of the servomotor housing in short-term operating modes S2 and S3 (in accordance with GOST IEC 60034-1-2014) in compliance with the time parameters specified in the operating instructions. In continuous mode S1 and continuous-periodic modes S4-S10, forced air flow may be required to blow the servomotor housing, the intensity of which depends on the selected operating mode and the parameters of the repeating cycles.
To control servomotors of versions sEM-07 and sEM-07L, the custom servo drives use universal or specialized 3- or 6-phase frequency converters designed for vector control of synchronous multi-pole servomotors with external feedback.
Servomotors of the sEM-07 series have the following modifications:
sEM-07 is a standard air-cooled version with basic features. The priorities are low price and maximum import substitution while ensuring high specific characteristics.
sEM-07L – customized air-cooled modifications with improved or maximum specific characteristics relative to standard sEM-07 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 better specific characteristics. As a rule, they are produced in limited quantities due to the relatively higher cost of products of this modification.
