Note: ① There are three specifications for the 802 motor frame, with the same motor installation dimensions but different electromagnetic designs. (② To obtain the adjustment range of the variable speed motor, a small amount of stable excitation winding is allowed.

③ The intermittent duty cycle (S3) has a period of 5 minutes per cycle, with continuous excitation of the excitation field. ④ The maximum starting torque and maximum running torque can reach the maximum values considering other performance requirements.

⑤ The tolerance of the armature inertia torque GD is taken as a positive value.
