Aircraft
This was our third leg in the aircraft for the day and the previous crew reported no abnormalities. ZZZ was reporting windshear at 2;000 feet at 45 knots with surface winds below 10 knots in the same direction. Due to the windshear we conducted a Takeoff-1 takeoff with the engine anti-ice on. The takeoff roll was normal; at 400 feet I called for heading and then yaw damper at 500 feet. At 1;000 feet I called for speed 210; and then began to trim the nose down to 10 degrees of pitch. As I was doing this the nose was not coming below 15 degrees and the control forces were becoming stronger; to the point I had the yoke fully forward attempting to lower the nose. While I was doing this I was also attempting to pitch the trim from 8 nose up to nose down. The trim was cutting out after 3 seconds; but was not actually moving and providing insufficient trim. I attempted this 3 times and from each trim cutout the trim only moved 1 unit. As the pitch trim was barely moving and cutting out I thought there could possibly be a runaway so I held the red disconnect button and alerted the First Officer that there was a flight control malfunction.While holding the red disconnect I reduced the thrust levers halfway and was finally able to lower the nose. I then tried using the primary pitch trim again and it seemed to work normally. The rest of the flight was normal and I made a maintenance write up when we landed. I explained the entire situation to the maintenance controller and made a mutually agreed upon write up in the logbook.Seems to be some sort of common failure in the primary pitch trim; but only in flight with control surface resistance. I had a similar experience in [a different] aircraft the previous trip; but only my First Officer had experienced it. I thought she was just struggling with the weight of the control surfaces during takeoff. I found out later that particular aircraft's pitch trim had failed on another flight afterwards.
EMB-145 Captain reported a pitch trim anomaly during climbout.
