Product Description:
The B & R Automation 8MSA7L.E1-M4 Synchronous Motor delivers 32.0 Nm rated torque and supports 2000 RPM speed. It offers precise motion control with a high resolution encoder. The motor is compatible with ACOPOS servo drives.
This 8MSA7L.E1-M4 synchronous motor has a rated torque of 32.0 Nm and reaches a maximum torque of 40.0 Nm. It runs at a rated speed of 2000 RPM with a rated voltage of 330 V. The rated current is 14.80 A while the peak current is 16.90 A. It is equipped with a 24 VDC holding brake that matches the motor’s rated torque of 32.0 Nm. The brake itself weighs 1.6 kg and contributes a moment of inertia of 5.56 kgcm². The motor is protected with an IP64 enclosure that offers reliable resistance to dust and water splashes. It uses an EnDat multi turn encoder with 512 lines and 4096 revolutions per turn. The encoder provides a precision of ± 60 arcseconds and supports a frequency limit of 100 kHz or higher at -3 dB. This enables accurate position feedback and stable operation in dynamic applications. The motor is engineered for performance with seamless integration into servo systems.
This 8MSA7L.E1-M4 synchronous motor is recommended for use with ACOPOS 8V1320.00-x servo drives for optimal compatibility and performance. The thermal insulation class of the servo motor is F that is suitable for industrial temperature conditions. The recommended cable cross section of 4 mm² ensures secure and efficient power delivery. The combination of torque, speed and encoder features makes this 8MS series synchronous motor ideal for precision industrial automation tasks. The motor supports exact movements and controlled acceleration in demanding machine applications.
