The range of ST torque motors with high energy iron-neodymium permanent magnets has been designed for the direct drive without gearbox of servo-mechanisms of highly dynamic automated production machines. ST torque motors are characterized by the integration of the active parts of STK kit motors up to a diameter of 300 mm – namely their rotor and stator – in a frame with shields, ball bearings, encoders or resolvers, a hpollow, blind or solid shaft with cable or connector outputs.
ST torque motors therefore have the same advantages as STK motors kits in terms of compactness, torque-to-weight, volume-to-weight, precision and reliability. They offer the machine manufacturer a motor integration when there is no interest in doing it in the machine itself. This is particularly the case for machines in which there is no integration frame. One can in particular quote the case of carousels and test benches. Note also the strong interest of ST torque motors in the case of application of cyclic machines with low inertia due to the reduced inertia of the motors despite the high peak torques.
