Dynamic precision motors

Modern machine concepts require mechatronic solutions. B&R's 8MS three-phase synchronous motors have been specially developed for use in high-performance applications. They are now being used to produce consumer goods and products in the plastic, packaging, metal, food and beverage industries and then palletize them with material handling systems.The three-phase synchronous motors from the 8MSA and 8MSC 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.

8MS three-phase synchronous motors

• NdFeB permanent magnets
• Sinusoidal commutation with EnDat encoder or resolver as feedback unit
• 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
• Low 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 circular plugs
• Controlled by ACOPOS™ servo drives
