  • Linear actuator
    Patent number: 4037122
    Abstract: A linear actuator comprises a toothed magnetic motor bar and a motor element having a pair of E-cores on opposite sides of the motor bar. Rollers attached directly to the E-cores ride on the motor bar to maintain a fixed air gap between the motor bar and the pole faces of the E-cores. The E-cores are connected by I-shaped connector plates to hold the tooth relationship between E-cores. The connector plates also are flexible to compensate for variations in thickness of the motor bar.
