摘要: An engine-driven generator includes an internal combustion engine, a permanent magnet alternator and an AC to AC converter. The output frequency and voltage of the permanent magnet alternator are largely dependent on engine speed and the alternator load. The AC to AC converter converts the speed-dependent alternating potential developed by the alternator to another alternating potential whose frequency and voltage are largely independent of engine speed. Voltage regulation is provided by varying the engine speed in accordance with the load current. Frequency regulation is provided by frequency dividing the alternator output by an integer divisor that varies in accordance with engine speed. Additional voltage regulation is provided by deleting selected cycles of the alternator output current as needed to maintain the RMS output voltage within predetermined limits. A stepper motor coupled to the throttle of the internal combustion engine controls the speed of the engine in accordance with commands received from an electronic system control.

摘要: A motor mount for attaching a motor, such as a trolling motor, to a boat includes a bracket, a pair of pivotable support arms and a motor support. The bracket may be removably attached to the transom or to the bow of a boat. The bracket, the support arms and the motor support form a 4-bar linkage that permits the motor to be moved between a fully deployed or lowered position and a fully stowed or raised position. As the motor is moved between the deployed and stowed positions, it moves through a first, generally vertical translation phase of motion during which it maintains a generally vertical orientation, and a second, generally pivotal phase, in which it is rotated from the generally vertical orientation to a generally horizontal orientation. An intermediate stowed position is provided just beyond a transition point between the two phases of motion. The mount facilitates temporary removal of the motor from the water, such as for displacement of the boat between fishing spots, without requiring adjustment of the motor depth and without subjecting the motor mounting tube to excessive bending moments due to cantilevered extension of the motor.
摘要翻译: 用于将诸如拖钓电机的电动机附接到船的电动机支架包括支架,一对可枢转的支撑臂和电动机支撑件。 支架可以可拆卸地连接到艉板或船的弓。 托架,支撑臂和马达支架形成一个4杆连杆,允许马达在完全展开或下降位置与完全收起或抬起位置之间移动。 当电动机在展开位置和收起位置之间移动时,它移动通过第一,大致垂直的运动平移阶段,在此期间,电动机保持大致垂直的定向,以及第二,大体上枢转的相位, 取向到大致水平的方向。 在两个运动阶段之间的过渡点之外提供中间收起位置。 该安装件有助于从水中临时移除马达,例如在钓鱼点之间移动船只,而不需要调整马达深度,而不会由于马达的悬臂延伸而使马达安装管受到过大的弯矩。
