direct current electric motorの例文
- A "'homopolar motor "'is a direct current electric motor with two commutator but still requires slip rings.
- Prior to the refit, the propulsion power was fed to four direct current electric motors located in separate engine rooms, two in the stern and two in the bow, through an applied Ward Leonard drive system.
- Drive is from a direct current electric motor and universal hydraulic speed gears ( a manual mechanical drive is also provided in case of electrohydraulic failure; with the use of mechanical drive, elevation speed is 4.5?per second and the turret traverse speed is 4?per second ).
- Some BLDC ( brushless direct current electric motor ) 3 phase motors are variable speed and appear to achieve this using either frequency modulation of constant pulse width ( 50 % duty cycle ), constant voltage and constant current or by pulse width modulation at constant frequency, constant voltage and constant current.
- Other minor problems were the direct current electric motors which drove the gyroscopes, whose brushes wore down quickly and left carbon dust throughout the interior of the device, and the positioning of the control knobs, which meant the bombardier could only adjust side-to-side or up-and-down aim at a time, not both.
