Dynamic precision motors

Modern machine concepts require mechatronic solutions. The extensive range of products in the 8LS servo motor series from B&R provides users with possibilities to further optimize production and service processes. Self-cooling or externally-cooled models can be selected.

8LS three-phase synchronous motors

Three-phase synchronous motors from the 8LS series are permanently excited, electronically commutated synchronous motors for applications that require excellent dynamic characteristics and positioning precision as well as compact size and reduced weight.

• - Sinusoidal commutation with EnDat encoder or resolver as feedback unit
• - Now available with functional safety encoders
• - Three-phase winding with star connection
• - Compact sizes result in low weight
• - Minimum moment of inertia because of favorable rotor construction results in very good dynamic properties
• - High overload capability/peak torque
• - Optimized torque ripple
• - High dynamic torque at high speeds
• - Long life-span, all motor parts except for bearings are free of wear
• - Power dissipation generated in the stator diverted directly to the flange via the housing
• - Preloaded, grooved ball bearings which are sealed on both sides and greased
• - Complete motor system with stall torque ranging from 0.2 Nm to 115 Nm
• - Connection using two SpeedTEC circular plugs
• - Control via ACOPOS servo drives or ACOPOSmulti drive systems

8LS three-phase synchronous motors are not allowed to be connected directly to the power mains; they are only allowed to be operated in combination with ACOPOS servo drives or ACOPOSmulti drive systems.
