Johnson Electric Offers BTA Rotary DC Solenoids

Johnson Electric’s BTA actuator platform offers high speed controllability in rotary stroke applications. The BTA has a single phase coil with three stator poles and matching rotor pole. When the coil is energized, the poles align along the flux path. The three pole design allows a stroke of up to 45°. Since BTA technology does not require full stroke actuation, stops can be used to attain maximum life as well as optimum stroke / torque capacity.

Using simple pulse width modulation to control coil current, the BTA allows open or closed loop velocity and maximum position control. The BTA platform offers quiet operation due to the soft, shock-free cycling which eliminates the noise associated with end-of stroke mechanical stops. Very quiet operation, long life in excess of 100 million actuations and high power density make the BTA product family ideal for high speed, high throughput diverting and sorting applications that require low noise and zero downtime.

Johnson Electric Offers Rotary DC Solenoids

Johnson Electric is the world leader in Rotary Solenoid technology. Rotary solenoids are electromechanical devices that convert linear motion to rotary motion by virtue of three ball bearings that travel down inclined raceways. When the coil is energized, the armature assembly is pulled towards the stator and rotated through an arc determined by the coining of the raceways. These extremely high speed actuation devices provide very long life operation for the most challenging applications. With operating life up to fifty million cycles, a wide variety of sizes and custom engineering for life, speed, environmental conditions and torque requirements, the Rotary DC solenoid is ideal for a variety of markets and applications including door lock, vending machines, industrial automation and medical diagnostic equipment.
