Electric motors and compact rotary mechanisms often need small mechanical parts that support return movement, positioning, cable control, contact pressure, or torque assistance. Custom springs can help improve product function while keeping the structure compact.
Depending on the application, spring solutions for motor-related products may include power springs, constant torque springs, constant force springs, cable springs, and other custom spring designs.
Where springs are used in motor-related products
- Rotary return mechanisms
- Brush, contact, or pressure support structures
- Compact cable routing and cable return systems
- Positioning and reset mechanisms
- Small actuators and motor-driven assemblies
Power springs and torque springs for rotary movement
Power springs and constant torque springs are useful when a compact mechanism needs rotational return or controlled torque. They can store energy during rotation and release it to help the mechanism return or maintain movement.
Important design factors include torque value, working angle, arbor diameter, housing size, cycle life, lubrication, and installation method.
Constant force springs for compact linear movement
Some motor-related assemblies require linear force instead of rotary torque. Constant force springs can support sliding, balancing, or retracting motion in compact structures. They are useful when a relatively stable force is needed through a working stroke.
Cable springs for motorized equipment
Motorized equipment may include moving cables, sensors, or connectors. Cable springs can help manage cable return and reduce tangling or uncontrolled movement. This is useful in compact devices where cable routing must stay organized.
Design and testing requirements
Spring design for electric motors and rotary mechanisms should consider vibration, heat, friction, cycle life, available space, and assembly tolerance. Testing should be done in the real mechanism because surrounding parts can affect spring performance.
