Nd-Fe-B PERMANENT MAGNET D. C. TORQUE MOTOR

摘要

After d. c. torque motor which is applied to seat servo system and low speed servo system as actuator adopts Nd - Fe - B instead of electric exciting source, its technical performance is improved very largely.rnThis paper designs a Nd Fe - B Permanent magnet d. c. torque motor whose ceiling locked -rotor torque is 120000 g. cm, whose ceiling locked - rotor voltage (20℃) is 60 V. , whose torque susceptibiveness k>9. 458 kg. m/a and whose ideal no- load speed n < 115 r/m. After measuring sample machine , this paper gives out the comparative conclusions of this motor and its sample machine,this motor and its same type motor of Alni-co 8 magnet. This supplies some beneficial conclusions for producing high -performance d. c. torque motor of new generation.
