Rotary Transducers

CDA InterCorp’s Rotary Transducers provide high accuracy outputs for angular position, velocity, and acceleration requirements in today’s advanced systems. These components deliver precise output performance in small size and weight. High grade stainless steel construction, class H220 insulation system, and brushless design assures reliable performance under the most severe operating conditions. Additional features include a wide operating range of -80° C to +220 &#176 C, high vibration and shock capacity, highvelocity and high acceleration capacity, high signal to noise ratio, continuous rotation, and a wide selection of output formats.

Description / Applications: Like the RX, the Control Resolver (RC) is useful in orthogonal axis translation. However, the RC is stator excited (S13 & S24) with sine-cosine voltages, and the motor output varies sinusoidally with rotor position. The RC may be driven off on an RX, or off a system gyro with sine-cosine components. RC’s are particularly useful in servo control applications, where the rotor output is used for amplifier signal input, in closed loop motor control systems.

Description / Applications: Resolver Transmitters are utilized in translating angular rotor position into orthogonal (sine-cosine) components. The two wire rotor (R12) is excited with fixed voltage and frequency, and the stator (S13 & S24) output voltages vary sinusoidally with the rotor position.

With the advancement of Resolver to Digital converters, these devices are becoming very popular in control and position sensing requirements, in advancing high reliability systems.
