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.
Features
Wide temperature range
Built-in type : -55∼+155°C
Shaft type : -30∼+100°C
Temperature compensation type (BRT): -10 ∼ +80 °C (For details, please refer to each individual specification.)
Superior environment resistance
Vibration : 196m/s2{20G} at 10Hz ∼500Hz, for 2 hours to each of three axes.
Shock : 981m/s2{100G} for 6ms, 3 times to each of 6 axes, 18 times in total
Humidity : 90% RH or above at 60°C
High speed rotation
Built-in type : 10,000min-1(r/min)
Shaft type : 6,000min-1(r/min)
Allowable rotation speed of some types may differ from the above values. For details, please refer to each individual specification. In addition, types exceeding 10,000min-1(r/min) are also available.
High reliability
Resolver has the similar structure to electric motors but has high reliability because of no winding coil on its rotor. In particular, the built-in types are free from maintenance because ball bearings are not installed in them.
Absolute position detection
Long-distance transmission
Robustness against noise enables long-distance transmission
Capable of compact incorporation
The use of built-in types of Resolver minimizes housings of motors. Best suited for compact design
Multi-polar types are available.
