Commonly used in: 桥/门式起重机起升与大车机构、高温高湿及沿海环境的变频驱动. Requirements for span, duty class and protection vary a lot by site — always specify against your real duty.
过载/散热差/绝缘降；降载、强冷、升 H 级。
制动逻辑错或刹车片磨；调抱闸、变频加制动单元。
参数错/干扰；对号调试、屏蔽线接地。
新项目优先变频鼠笼（免碳刷、省维护），旧改可留绕线。
选 H 级绝缘+IP55+强冷，沿海加重防腐。
带编码器+失电抱闸，定位准且防溜钩。
按电机功率×1.1-1.2，起升加制动单元。
