31. Finally, hysteresis synchronous motors typically are ( essentially ) two-phase motors with a phase-shifting capacitor for one phase. 32. The rotor poles connect to each other and move at the same speed hence the name synchronous motor . 33. To achieve their top speed, the elevators in the Guangzhou CTF Finance Centre use permanent magnet synchronous motors . 34. The D-37C computer memory consists of a rotating magnetic disk driven by a synchronous motor at 6000 rpm. 35. My AR turntable simply had a synchronous motor so it was as line-locked as the stroboscope would have been. 36. The difference between the two types is that the synchronous motor rotates in exact synchronism with the line frequency. 37. The installation powered a synchronous motor at Telluride, Colorado with the motor being started by a Tesla induction motor. 38. One type of synchronous motor is like an induction motor except the rotor is excited by a DC field. 39. The speed of a synchronous motor ( used in talk ) 23 : 52, 16 March 2015 ( UTC) 40. They have been replaced by variable frequency, synchronous motors manufactured by EMICC that operate between 350 and 1800 rpm.
