Segmented resolver is an induction transformer type precision and high accuracy angular position sensor. It is basically a rotary feedback device used in limited angle rotation like fire control systems, pitch and role platforms, position control systems, etc. It as low as 5-10 arc seconds. The reduced arc permits decrease in assembling time, material saving and lower cost. The unique design of segmented resolver is an extension of full-rotation resolver configuration and provides accurate position data in limited angle application. Segmented resolver is manufactured by M/s Srijan Control Drives, Pune.
Wheel Speed Transducer
Wheel speed transducer is a wheel speed-sensing device that operates on the principle of variable reluctance with DC excitation. It is designed to provide two identical signals generated independently within the transducer with full electrical isolation between them. The electrical signal provided by the wheel speed transducer corresponds to the wheel speed equipment. The transducer is used in aircraft break management applications. Wheel speed transducer is manufactured by M/s Transducers & Allied Products, Bangalore.
DC Motor is used to drive electromechanical actuators. These actuators are used to drive the flight control surfaces for effecting steering of the flying vehicles in pitch, yaw and roll control. The DC motor works on 28 V DC, conforms to size 23, with a reduction gearbox of 64: 1. The motor employs samarium-cobalt magnets, brush type commutator and planetary gearbox. The motor is fully qualified to meet the environmental standards as per MIL-STD-810C. DC motor is manufactured by M/s Srijan Control Drives, Pune and M/s Delta Technologies, Secunderabad.
