Product Description:
The 11CT-300-D-1A/10 Resolver functions as a precision rotary electrical transformer. It is intended for motion control applications in industrial automation from Dynapar’s Harowe Servo Series. The standard operating frequency is 400 Hz, while it accepts 3-phase input with 90 volts at the stator. The rotor generates 57.3 volts to provide accurate position information through its single-phase output.
The 11CT-300-D-1A/10 resolver contains a 3/8" shaft that extends 1" from the outer diameter with a 1/8" diameter. It depends on five wires with colored sheathing for both signal and power transmission purposes. The industrial-grade stainless steel housing uses solid mechanical elements to stay functional in harsh factory conditions. The resolver carries IP40 ingress protection to function correctly in dry environmental conditions. The instrument's weight reaches 100 grams to serve its purpose of providing low rotational inertia. The position sensor functions through analog signal processing rather than digital encoding. However, a digital encoder is not integrated into the 11CT-300-D-1A/10 resolver. This resolver functions effectively between -55°C and +125°C and up to +125°C for its operational temperature range. The resolver contains brushless internal components that reduce wear and maintain an extended operational lifetime. The aluminum housing has excellent thermal conductivity and strengthens mechanical stability. The unit's resolution is defined by the analog nature of sine and cosine outputs.
The 11CT-300-D-1A/10 resolver provides exceptional reliability. However, it does not contain onboard electronics that would face electrical noise problems. The tolerance to shock and vibration meets established military-grade standards. The product fulfills all requirements defined by MIL-STD-810 for serving demanding rugged applications. The resolver operates frequently in servo motor and gimbal system feedback control systems. The long service life combined with reliability attributes makes this component to critical systems where trust is essential.
Frequently Asked Questions about 11CT-300-D-1A/10:
Q: Why is IP40 protection sufficient for 11CT-300-D-1A/10 resolver?
A: IP40 protection is adequate for dry, enclosed factory settings. It safeguards internal components against solid foreign objects over 1 mm.
Q: How does the resolvers weight contribute to its performance?
A: Weighing just 100 grams, the 11CT-300-D-1A/10 reduces rotational inertia. This supports quick response times in dynamic control systems.
Q: What advantage does the 3/8" shaft offer in the 11CT-300-D-1A/10 resolver?
A: The 3/8" shaft with 1/8" diameter extension supports precise mounting alignment. It enhances torque transfer while minimizing mechanical play.
Q: How does the five-wire configuration benefit 11CT-300-D-1A/10 resolver operations?
A: The five-wire setup separates power and signal paths, reducing interference. It supports consistent analog output under varying load conditions.
Q: What is the role of analog signal processing in 11CT-300-D-1A/10 resolver?
A: Analog signal processing allows smoother and more continuous position feedback. This ensures precision in servo control systems without digital quantization errors.
