Abstract
An electric motor, having a coil without iron-core and having an integrated electronic control device, has a sine commutator supplying the electric motor with sine-shaped currents or voltages. The control device has an rpm control with which a magnitude of the sine-shaped currents or voltages is preset. The electronic control device also has a position control for the motor shaft.
Claims21
Electric motor having a coil without iron-core and having an integrated electronic control device (9), wherein said electronic control device (9) has a sine commutator (28) supplying said electric motor with sine-shaped currents or voltages.
Electric motor having a coil without iron-core and having an integrated electronic control device (9), wherein said electronic control device (9) has a sine commutator (28) supplying said electric motor with sine-shaped currents or voltages, said control device (9) comprising an analog terminal (32) for rpm set point input, said electric motor further comprising a logarithmic amplifier to which said rom set point input is supplied and subsequently digitalized in an A/D converter with logarithmic reversal by a mathematical algorithm.
Electric motor having a coil without iron-core and having an integrated electronic control device (9), wherein said electronic control device (9) has a sine commutator (28) supplying said electric motor with sine-shaped currents or voltages, said control device (9) having an overvoltage control (31) connected to said sine commutator (28), wherein said overvoltage control (31) changes the angle between the rotor (13) of said electric motor and a rotary field.
