Linear Motors

Optimal Use of Magnetic Flux
The tubular design of Copley Linear motors makes optimal use of the magnetic flux. All of the coils cut all of the flux at right angles. A large air gap is possible and the symmetrical design is unaffected by misalignment.

Superior Thermal Charecteristics
The tubular motor has superior thermal efficiency radiating heat uniformly. Copley motors have a high duty cycle capability without the need for forced air cooling.
