Narrative:

While departing ZZZ on the abc 3 departure, we were in a left turn direct abc VOR. Climbing through 7500 ft at 210 KTS with slats extended at 30 degree bank, first officer called for IAS 250 KTS, set speed 250 KTS, bank angle 15 degree, slats retract, after takeoff check. As he was accelerating and using the primary trim, the trim motor would not respond. We checked the trim switch on my side, the suitcase handle switch and the alternate trim switch on center pedestal, with no response. I asked him to slow to 200 KTS and extend slats. We asked for extended downwind and that we were returning to ZZZ. We received approach clearance and landed using flaps 40 degree and a bug speed of 140 KTS. The aircraft flew fine at that speed about 15 pounds of pressure.
