Abstract

The subject matter described herein relates to a system including a power-limiting controller (306) and a motor (308). The power-limiting controller (306) is configured to modulate unmodulated power (312) received from a power source (304). The power-limiting controller (306) modulates the unmodulated power (312) based on a throttle position signal (310) to provide modulated power (314). The modulated power (314) is drawn by the motor (308). Further, the power-limiting controller (306) adjusts the modulated power (314) based on a predefined range of speeds (403) of the motor (308), such that an output power of the motor (308) is maintained within a predefined power limit (412).

Claims

AMENDED CLAIMSReceived by the International Bureau on 08 February 2010 (08.02.10)
1. A system comprising: a power-limiting controller (306) configured to modulate unmodulated power (312) received from a power source (304) based on a throttle position signal (310) to provide modulated power (314); and a motor (308) to receive said modulated power (314); characterized in that, said power-limiting controller (306) adjusts said modulated power (314) based on predetermined range of speeds (403) of said motor (308) and maintains an output power of the motor (303) within a predefined power limit (412) by controlling an input current from said power source (304) based on predetermined values of current.
2. The system as claimed in claim 1, wherein said power-limiting controller (306) further determines whether a motor speed is within said predetermined range of motor speeds (403),
3. The system as claimed in claim 2, wherein said power-limiting controller (306) further adjusts said modulated power (314) based on said motor speed by varying a current drawn by said motor (308), wherein the motor speed is within said predetermined range of motor speeds (403).
4. The system as claimed in claim 1, wherein said motor (30S) is a brush less direct current motor.
5. The system as claimed in claim 1, wherein said power-limiting controller (306) receives said unmodulated power (312) from a battery.
6. A method comprising: receiving unmodulated power (312); modulating said unmodulated power (312) based on a throttle position signal (310) to provide a modulated power (314) to drive a motor (308); determining whether a motor speed is within a predetermined range of motor speeds (403); adjusting said modulated power (314) based on predetermined range of speeds of said motor (308); controlling an input current from power source (304) based on predetermined values of current; and maintaining an output power of said motor (308) within a predefined power limit (412).
7. The method as claimed in claim 6, wherein said adjusting of said modulated power (314) is achieved by varying a current drawn by said motor (308) according to a range of predetermined values of current.
8. The method as claimed in claim 6, wherein said adjusting of said modulated power (314) is achieved by pulse width modulation.
9. The method as claimed in claim 6, wherein said modulation of said unmodulated power (312) from said power source (304) is achieved by pulse width modulation.
10. The method as claimed in claim 7, wherein said range of predetermined values of current corresponds to said predetermined range of motor speeds (403).
