Small-batch customization is also available for special voltage, speed, gear ratio, output shaft, encoder, and driver requirements.<\/p>\n\n\n\n
For an inquiry, provide at least: Rated Voltage + Continuous Torque + Peak Torque + Speed + Peak Duration + Duty Cycle + Holding Time + Size Limit + Estimated Quantity<\/p>\n\n\n\n
In particular, do not provide only stall torque. For robot or dexterous-hand projects that must hold a load continuously, holding time should be specified separately so that the thermal load of the motor and gearbox can be properly assessed.<\/p>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
For most DC motor and DC gear motor applications, selection should first focus on the torque that can be used continuously at the target speed. Depending on the manufacturer, this parameter may be labeled Rated Torque, Nominal Torque, or Maximum Continuous Torque. Stall Torque is better used to assess the zero-speed limit, jammed conditions, starting margin, and the maximum current the driver must handle; it should not be used directly as the normal continuous operating torque.<\/p>\n\n\n\n
For applications such as robot joints and dexterous hands that experience short-duration high loads, Stall Torque or short-duration capability near the stall region can be used appropriately, but Peak Duration, Duty Cycle, Current Limit, and heat-dissipation conditions must all be considered. In particular, when an actuator must hold a load for a long time at zero speed, confirming only that Stall Torque is sufficient does not demonstrate that the motor is suitable for the task.<\/p>\n\n\n\n
Therefore, when engineers compare rated torque vs stall torque, the first question should not be ‘Which number is larger?’ but rather: At what speed must this torque be produced, and for how long? Only after these two conditions are defined do the other torque parameters in the datasheet become truly meaningful.<\/p>\n\n\n\n
FAQ<\/h2>\n\n\n\nQ1:Can I Use Stall Torque to Select a DC Motor?<\/h4>\n\n\n\n
Generally, Stall Torque should not be used directly as the normal selection torque. For continuous operation, first check the Rated Torque, Nominal Torque, or Continuous Torque at the target speed. Stall Torque is more suitable for assessing the zero-speed limit and short-duration overload capability.<\/p>\n\n\n\n
Q2: Is Starting Torque the Same as Stall Torque?<\/h4>\n\n\n\n
Not exactly. When a simple DC motor is powered directly without current limiting, its operating condition at the instant of starting may be close to stall, so Starting Torque may approach Stall Torque. However, driver current limiting, PWM, soft start, and other factors will change the actual starting torque.<\/p>\n\n\n\n
Q3:How Long Can a Motor Operate at Stall Torque?<\/h4>\n\n\n\n
There is no fixed duration applicable to every motor. At stall, Back EMF is close to zero, and the current and I\u00b2R copper loss rise rapidly. The permissible duration therefore depends on the winding, Current Limit, Thermal Time Constant, heat dissipation, and initial temperature. Ordinary Stall Torque should not be interpreted as sustainable operating torque.<\/p>","protected":false},"excerpt":{"rendered":"
When reviewing a DC motor or DC gear motor datasheet, engineers often encounter two values that differ significantly: Rated Torque and Stall Torque. If a motor has a rated torque of only 2 N\u00b7m but a stall torque of 5 N\u00b7m, should the design calculation be based on 2 N\u00b7m or 5 N\u00b7m?
