Six-Phase Motor Controller
Abstract
Six-Phase Motor Controller Solution
In recent years, with the rapid development of special vehicles, ship electric propulsion, and underwater unmanned equipment and other fields, strict requirements have been imposed on the reliability and power density of electric drive system. The core pain points exposed by traditional three phase motor drive systems under extreme working conditions need to be urgently addressed:
Low fault tolerance: Once a single phase fault occurs in the traditional three phase system, the system will completely shut down, unable to meet the redundant requirements for "absolute safety" of special equipment;
Size limitation and heat dissipation : The internal space of special equipment is extremely small. Traditional controllers are large in size and are prone to performance degradation due to heat accumulation under high load operation.
Poor adaptability to extreme environment: When facing harsh environment such as high frequency vibration, salt fog, and extreme temperature differences, the electrical and physical structures of conventional civilian level controllers are highly prone to failure.
power solution limited: traditional solutions are monotonous and difficult to balance both cost and experience.
Solution
In response to the demanding requirements under special working conditions (such as unmanned underwater operations in research institutes and other projects), SAVCH has launched high performance six phase motor controller and integrated drive solution, reconfiguring the power drive modules of special equipment:
Wide power coverage and precise control: It offers full power range coverage from 0.5Kw to 400Kw and adopts six phase dual mode vector control (FOC/SVPWM) to meet the driving requirements of all scenarios.
Dual mode high efficiency thermal management: Integrated liquid cooling and air cooling dual mode. The bottom shell radiator adopts 7075 aluminum alloy integral hollowing process and friction stir welding to ensure stable output under extreme working conditions.
Poor adaptability to extreme environments: The entire machine, through a special potting process and a 10G gravity acceleration shock resistance design, combined with strict PCBA "three proof" spraying, is not afraid of extremely harsh environments.
There are two power output schemes for the power output section: the integrated reducer motor and the direct drive motor. You can choose based on the goal of cost priority or experience priority.
Product Highlights
Redundant safety: Dual winding design ensure that even in the event of a single phase fault, the system can still maintain 50% of the power output, guarantee the smooth operation of critical system.
High torque density: the torque under the same volume increased 30% +, and electromagnetic torque pulsation rate control in < 5% of the extremely low levels ;
High efficiency and energy saving: The overall system efficiency is up to 95% or more, superior to traditional three phase motors. Copper loss and iron loss are reduced by 15%-20%, and the comprehensive energy consumption is saved by 10%;
Fast dynamic response: It can achieve millisecond level load change response, with control accuracy improved by 20%, meeting the instantaneous power burst requirements of special equipment;
Strong communication anti-interference: CAN communication lines use twisted pair cables and add isolation and selected high specification communication chips are selected to ensure absolute stability of data transmission in strong magnetic field environments.
