Abstract
More reliable torque motors are provided with reduced susceptibility to external vibration while also maximizing structural damping without requiring the usual potting with resins and adhesives, bolting hardware, etc. Enhanced torque motor dependability is achieved by clamping torque motor assemblies rigidly in place through frictional forces generated by a generally thin walled tubular housing preferably having surface elevations which compressively engage the motor assembly through an interference fit. The more reliable torque motors are especially useful in aviation applications as actuators for servovalves, and wherever highly reliable virtual fail-safe performance is required.
