Abstract

PURPOSE:To detect speed signals without use of any speed indicator or the like by full wave rectification of the secondary output of a resolver connected to a rotary driving system with differentiation through an LPF after the wave form shaping and synchronous rectification thereof. CONSTITUTION:Sine waves E1 and E2 or square waves SQW1 and SQW2 as excitation voltage are applied to a sine winding 11-1 and cos winding 11-2 as the primary side of a 2-phase resolver 11 from an exciting power source 12. The output of the resulver 11 is applied to a waveform shaping circuit 14 through BPF13 to make a square wave the same in the cycle and phase as the output voltage Eo. Then, it is inputted into a synchronous rectification circuit 15A while the square wave SQW1 is applied thereto as rectification signal. The output is provided to a differentiation circuit 17A through an LPF 16A and further inputted into a signal processing circuit 18'. The speed signal of the rotary driving system can be detected by processing signals with full-wave rectification in the circuit 18' or by changing over the output of the differentiation circuits 17A and 17B with a switching circuit 18.
