Admotec Transformer RO3620 Series

Admotec Transformer RO3620 Series

The Admotec Precision RO3620 series is a high-performance rotary transformer (Resolver) launched by the Swiss company Admotec, using ROTASYN ® Solid state rotor technology is designed for high-precision angle/position feedback in harsh environments and is widely used in fields such as aerospace, new energy vehicles, industrial servo motors, and semiconductor equipment.

core strengths

1. Solid rotor without winding design

• No risk of wear and tearThe rotor is made of solid metal (such as steel or titanium alloy), without winding, slot, or bonding, eliminating the risk of winding loosening, wear, or ejection during high-speed rotation. The theoretical lifespan exceeds 100000 hours and operates in the same cycle as the motor.

• Low inertia designThe rotor inertia is extremely low, reducing the load and energy loss during high-speed rotation, improving the motor start stop response speed (such as reducing the start stop time by 30% for the RO2010 model), and ensuring more stable operation.

• Compact installationThe frameless design allows the stator to be directly pressed onto the motor housing, and the rotor to be fitted onto the spindle, saving axial space (such as the RO3620 model with an axial length of only 12mm) and adapting to the compact structure inside the motor.

2. High precision and dynamic adaptability

• Angle measurement accuracyThe conventional model has an accuracy of ± 30 arc minutes (about 0.008 °), while the multipole version (such as 16 pairs of poles) has an accuracy improved to ± 4 arc minutes (about 0.001 °), meeting the nanometer level positioning requirements (such as semiconductor lithography machine objective focusing motor).

• High speed adaptabilityThe RO2010 model supports a speed of 160000 RPM, while the RO3620 model supports 100000 RPM, covering the full range of requirements from micro high-speed servo motors to industrial high-speed transmission motors.

• dynamic responseSignal delay<5ms, supports high-frequency position updates (such as robot joint control requiring an update rate of 500Hz or higher), compatible with closed-loop control systems.

3. End environment tolerance

• Wide temperature operationThe K-class version can operate stably within the range of -196 ° C to+220 ° C, and can withstand the heat generated by long-term motor operation and external environmental temperature fluctuations (such as aerospace engine actuators).

• Resistance to vibration and impactSome models are equipped with sealed cables and connectors, which can withstand 20G impact and 10G vibration, suitable for industrial scenarios with multiple vibrations and impurities (such as heavy-duty rolling mill motors).

• Medium resistance characteristicsThe rotor can be directly immersed in hydraulic oil, fuel, and other liquids to operate, solving the sealing problem of high-speed motors in hydraulic systems (such as measuring drill pipe speed on oil drilling platforms).

• High voltage toleranceThe RO5032 series can withstand pressures up to 1600 bar, meeting the requirements of harsh scenarios such as deep-sea exploration and nuclear energy equipment.

4. High compatibility and customized services

• Electrical interface compatibilityDirectly replace traditional brushless rotary converters without changing the controller, reducing integration costs.

• Duplex redundancy designCan integrate two independent measurement channels to meet SIL safety level requirements for aviation, nuclear power, and other industries.

• Customized optionsSupport variable ratio matching, temperature range expansion, sealing level improvement, anti vibration parameter adjustment, etc., suitable for special working conditions such as high temperature, high pressure, and high speed.

Typical application scenarios

1. aerospace

• Engine control, actuators, flight control system, operating temperature range -55 ° C to+180 ° C.

• Satellite antenna positioning, unmanned aerial vehicle propulsion system, capable of withstanding strong vibrations and terminal temperatures.

2. new energy vehicle

• Electric drive system, fuel cell air compressor, suitable for high temperature and strong electromagnetic interference environment in the motor compartment.

• The electric power steering system adjusts the magnitude of power assistance based on the angle of the steering shaft, ensuring precise response with high-precision characteristics.

3. Industrial Automation

• High speed machine tool spindles (such as precision grinding centers with speeds exceeding 120000 RPM) and robot joints provide nanoscale positioning feedback.

• Wind power/photovoltaic/flywheel energy storage system, used for high-speed permanent magnet synchronous motors and pitch control.

4. Energy and Deep Sea Exploration

• The control rod drive mechanism and reactor cooling system valves of nuclear power plants have radiation resistance, sealing and pressure resistance characteristics.

• Deep sea downhole tools and underwater actuators, with a pressure resistance of over 70 bar, suitable for high-pressure environments.

5. semiconductor manufacturing

• The objective lens of the lithography machine is focused and the crystal frustum is positioned. The resolution of the multi pole version is improved to ± 4 arc minutes, and it is combined with high bandwidth RDC to achieve nanometer level angle closure.

• The high-pressure process valve control of the etching machine reaction chamber can withstand a pressure of 1600 bar and corrosive gases such as CF4 and SF6.
