Angle sensors (Analog output) - Radion Electronics

A resolver is an angle sensor that outputs rotational angles as two-phase AC voltages (analog signals). It features structurally high environmental resistance compared to other sensors due to its simple design comprised of only an iron core and a coil.

Features:
Wide operating temperature range
Excellent environmental resistance
Rotatable at high speeds
High reliability
Absolute value position detection
Long-distance transmission available (Highly resistant to noise)
Compact assembly
Resolver System Structure

Type:
BRX model (Amplitude-modulated)
Single-phase induced/two-phase output
BRT model (Phase-modulated)
Two-phase induced/single-phase output
BRS model (Amplitude-modulated)
Two-phase induced/two-phase output

Brushless resolvers (FA-SOLVER®）
Brushless resolvers (FA-SOLVER®）

Brushless resolver can be used for high accurate feedback of position and speed sensing, and pole detection of motor. Through their features of resistance for harsh environment and other reasons, they are used with motors for machine tools and robots, in steelworks. We collectively call these brushless resolvers as FA-SOLVER®, and renewed their lineup to cope with a new FA era.

Brushless resolvers (Smartsyn)
Smartsyn is an angle sensor that converts rotational angles into electric signals.

Smartsyn is a brushless resolver based on an innovative winding method (National/Foreign Patent registered) our sophisticated design and production engineering developed. The traditional winding has been performed only by hand but our new method has enabled automatic winding by machine, thus realizing high productivity, low cost, high reliability, and excellent electrical properties.

Positioning Systems (Enviroment Resistance)

Sensors (Transmitters) of the system come with resolvers excellent in environment resistance or encoders with high accuracy and high resolution. Combining the sensors with converters, we provide you with highly accurate and reliable systems. Depending on the combination with the converter, three types; a 1 turn type, a multi-turn type, and a 1 turn/multi-turn switching type are available.

Steel, Crane, Packing Wrapping, Food, Printing machine, Press machine

Over the past 70 years, we have been engaged in research, development, and manufacture of FA equipment such as Synchro, Resolver, Gyro, and so on. Based on long-standing experience and a wealth of know-how accumulated through the production of control equipment for steel plants and water processing, we proudly propose a smart position detecting system" Smartcam". In addition to the conventional systems, Smartcam has new lineups equipped with absolute encoders for higher accuracy and resolution. We recommend Smartcam, with confidence, as the right position detector that ensures you high reliability, safety, and labor efficiency.

Resolver / Digital converters (Smartcoder)

Smartcoder is a R/D (Resolver to Digital) conversion IC, which converts resolver signals into digital absolute position angle signals. It is usable in a wide range of applications, including vehicle/robot/machine tool related applications, in combination with brushless resolvers such as our Smartsyn and Singlsyn.

VR Type (Singlsyn)

VR Type (Singlsyn)

It is ultra-thin absolute type angle detector with a strong high reliability in high temperature , vibration and shock . The Singlsyn has higher reliability and can be produced at lower cost as it does not have a coil on its rotor. Forming the rotor core into a special shape and changing the width of the gap between the rotor core and the stator core generates changes in the amplitude of the output voltage. The Singlsyn can be installed in a minimal amount of space due to the ultra-thin structure of the built-in model. (Singlsyn is our trademark for VR type Resolver.)
