Drawbridge motor & controller upgrades
Drawbridge motor & controller upgrades
(OP)
Does anyone have experience with upgrading the control system & drive motor for a motor operated drawbridge? We are investigating upgrades to an existing drawbridge that uses a 30 HP wound rotor motor and a resistor bank for speed control. Is anyone familiar with using an "off the shelf" induction motor for such an application, & what sort of control system is typically used? I would welcome any ideas and recommendations.

I have to assume there is some kind of mechanical brake with interlocking, similar to what would be on a hoist drive for safety.

I am in no way trying to promote their services, this is just a project I knew about.
