It’s easy to take feedback devices for granted. However, the impact this seemingly minor component can have on a system’s accuracy, performance, reliability, and ease of integration is hard to ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

Abstract: Sinusoidal encoders and resolvers encode position information by providing a pair of sine and the cosine signals. In order to determine the position information, suitable phase demodulation ...

Among the mechanical components that go into the design of the world’s two million different kinds of medical devices, consider the motor to be an unsung hero. Embedded inside a medical device, the ...

A new magnetic digital encoder featuring 14-bit resolution, differential outputs, and a speed range of up to 200-k e-RPM offers accurate and cost-effective position sensing for various robotic and ...

Position and angle sensors are used in several electric vehicle (EV) components, including the traction motor and drivetrain, heating, ventilation, air-conditioning (HVAC) compressor, steer-by-wire, ...

Astrosystems' (Lake Success, NY) resolver-based multiturn Astrocoder/150 provides 16-bit position accuracy over 64 turns. Geared dual resolvers are unaffected by noise or vibration and output reliable ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...
