The spindle can be driven by multiple motor types in a screw torque module. Which option lists possible drive types?

• A. DC motors only
• B. AC motors only
• C. AC, DC, or Pneumatic drives
• D. Hydraulic drives only

Answer: (C)

The driving method for the spindle in a screw torque module can vary, and the design supports multiple actuation options. Electric drives come in two common forms: AC motors, which provide simple, reliable high-speed rotation, and DC motors, which offer precise torque control at lower speeds. Pneumatic drives use compressed air for actuation, offering robust and quick responses in many tooling setups. The option that lists AC, DC, or Pneumatic drives correctly reflects these available choices, covering the electric (both AC and DC) and pneumatic options commonly used with such modules. The other choices restrict the drive types to a single technology or to hydraulic, which isn’t the standard set described here.
