Abstract: A method for controlling a ceiling fan motor includes: setting a target value of rotational speed and a limited value of rotational torque; controlling the ceiling fan motor to operate; obtaining operation information of the ceiling fan motor; calculating a current rotational speed and a current rotational torque according to the operation information; determining whether the current rotational torque is greater than or equal to the limited value of rotational torque; performing a constant rotational torque operation when the current rotational torque is greater than or equal to the limited value of rotational torque; determining whether the current rotational speed reaches the target value of rotational speed when the current rotational torque is less than the limited value of rotational torque; performing a constant rotational speed operation when the current rotational speed reaches the target value of rotational speed; and increasing torque current of the ceiling fan motor.

Abstract: A scroll compressor includes an orbiting scroll member, a non-orbiting scroll member, a spacing block, and an annular pressure piece. The non-orbiting scroll member is disposed on the orbiting scroll member. The spacing block has a first annular recess and at least one first through hole. The spacing block is disposed on the non-orbiting scroll member. The first through hole is located within the first annular recess and penetrates the spacing block. The annular pressure piece has a second annular recess and at least one second through hole. The second through hole is located within the second annular recess and penetrates the annular pressure piece. The annular pressure piece is accommodated within the first annular recess. One side disposed with the second annular recess of the annular pressure piece faces the spacing block. The annular pressure piece is located between the spacing block and the non-orbiting scroll member.
