Disc armature motors outperform conventional iron cored designs

Disc armature motors outperform conventional iron cored designs

AST brushed DC servo motors use ironless disc armature technology for exceptional speed and rapid positioning performance in a very compact design. Available from Heason Technologies, these zero-cogging, 'flat' motors have minimal inductance, near full torque throughout the rated speed range and a high current overload capability that allows instantaneous, sub-millisecond torque for an acceleration performance over 10x that of conventional iron-cored DC motors.


The low inertia motor design has an unparalleled torque-to-inertia characteristic and a typical move from standstill to 3000 rpm can be achieved in only 45 degrees of motor rotation. Low inductance also results in much longer brush life than iron cored motors. The complete range covers four frame sizes from around 90mm to 190mm diameter (size 6, 9, 12 and 16) with nominal lengths from 27mm to 63mm.
