1 General description
Three-phase synchronous motors from the 8JSA series are permanent magnet, electronically commutated syn-
chronous 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
•
Star-connected three-phase winding
•
Small construction volume, thus low weight
•
Minimized moments of inertia due to favorable rotor design, thus very good dynamic properties
•
High overload capability / peak torques
•
Optimized torque ripple
•
High dynamic torque at high speeds
•
Long service life, motors wear-free except for ball bearings
•
Direct power dissipation in the stator via the housing to the flange
•
Preloaded deep-groove ball bearings, closed on both sides with grease lubrication
•
Continuous motor series with stall torques from 0.84 Nm to 53 Nm
•
Connection via two speedtec circular connectors
•
Control via B&R drive systems
