ELEVATOR MOTOR DRIVE TOLERANT OF AN IRREGULAR POWER SOURCE |
摘要 |
A hoist motor (12) for an elevator (14) is continuously driven from an irregular power supply (16). A regenerative drive (10) delivers power between the power supply (16) and the hoist motor (12). A controller (11) measures a power supply voltage in response to a detected change in the power supply voltage and controls the regenerative drive (10) to adjust a nominal motion profile of the elevator (14) in proportion with an adjustment ratio of the measured power supply voltage to a normal power supply voltage.
