Key Takeaways:
Direct-drive torque motors eliminate belts, gears, and their backlash and vibration. Paired with a hydrostatic film, they give high low-speed torque and clean motion for precision rotary tables.
Hidden Cost的皮带与Gears
皮带-与齿轮-driven 回转 tables introduce 反向间隙, elastic wind-up,与transmitted 振动. At low feed they can 也 exhibit stick-slip. 这些 defects directly limit achievable 精度.

直驱 on 静压 Film
A 直驱 力矩电机 couples rotor straight以 table. 丸作精工使用 485SJM-1350BH delivering 1350/2400 N·m, giving strong torque at low speed采用no mechanical reduction. Combined采用 无接触 油膜, 运动为平稳 from first micron的回转.
结果
No 反向间隙, no 皮带 wear,与no stick-slip means table tracks commanded position exactly—exactly what sub-micron 回转 work demands.
