Abstract
A linear motor actuator includes a plurality of stators mounted stationary relative to one another along a common actuation axis. A translator rod is mounted to the stators for linear motion relative to the stators along the actuation axis, wherein each stator is magnetically coupled to the translator rod to drive motion of the translator rod along the actuation axis.
Claims19
A method of controlling a linear actuator comprising:
- slaving a plurality of slave stators in a linear motor actuator to a master stator in the linear motor actuator, wherein each stator is magnetically coupled to a common translator rod to redundantly drive motion of the translator rod along an actuation axis;
- detecting the master stator going off line;
- and
- reconfiguring one of the plurality of slave stators as a new master stator and slaving any remaining operational slave stators to the new master stator.
