●
High dynamics (owing to the favorable ratio of torque to inertia mass)
●
High overload capability (owing to the favorable heat dissipation from
the stator windings to the outside wall of the motor housing)
●
Peak torque utilizable across a wide speed range (owing to electronic
commutation)
●
Continuous start-stop operation possible with high repeat frequencies
(owing to electrical commutation)
●
Easy attachment to the machine (owing to flange according to DIN
42948)
●
Any installation position desired
●
Simple and fast startup (by data memory)
Design and Components
MKE motors are permanent-magnet motors with electronic commutation.
Special magnet materials permit the motors to be designed with low inertia
masses. The following figure shows the principal design of MKE motors.
