摘要： A motor control circuit (MC) comprising input terminals (IT1, IT2) to receive a rectified input voltage (Vrm), and output terminals (OT1, OT2) to supply a motor drive signal (Vm). A switching circuit (1) is alternately in an on-state (Ton) and an off-state (Toff) for intermittently coupling the input terminals (IT1, IT2) to the output terminals (OT1, OT2). A controller (2) controls the switching circuit (1) to be (i) in the on-state (Ton) during a first period in time (T1) when an amount of magnetic saturation of the motor is smaller than a predetermined value, and (ii) alternately in the on-state (Ton) and the off-state (Toff) to obtain a pulse width control of the motor drive signal (Vm) during a second period in time (T2) when the amount of magnetic saturation of the motor is larger than the predetermined value.

摘要： A method of manufacturing an electrical suction unit for use in a vacuum cleaner includes a turbine unit and an electrical motor with a rotor and a stator. The turbine unit is attached to the rotor and forms, together with the rotor, a rotatable part of the suction unit, which is rotatable about an axis of rotation. An amount of material is removed from the rotor and from the turbine unit to torque-balance the rotatable part of the suction unit. In this manner, the amount of material to be removed from the rotor to torque-balance the rotatable part is considerably reduced, so that the adverse influence of the removal of the material from the rotor on the performance of the electrical motor is limited.
