The difference between waterproof motor IP65 and IP67

Both IP65 and IP67 are completely dust-proof, but the water-proof grade is different:

IP65 prevents the injection of water from immersing, that is, prevent the water ejected from the nozzle from all directions from invading the electrical appliances and causing damage;

IP67 prevents water immersion during flooding, that is, the electric appliance is immersed in water for a certain time or the water pressure is below a certain standard, which can ensure no damage caused by flooding.


Advantages of Waterproof  Stepper Motor:

  • 1. The rotation angle of the motor is proportional to the input pulse.
  • 2. The motor has full torque at standstill.
  • 3. Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3 – 5% of a step and this error is noncumulative from one step to the next.
  • 4. Excellent response to starting, stopping, and reversing.
  • 5. Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.
  • 6. The motor’s response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
  • 7. It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
  • 8. A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.

Product Application Information


Computer controlled stepper motors are a type of motion-control positioning system. They are typically digitally controlled as part of an open loop system for use in holding or positioning applications.

In the field of lasers and optics they are frequently used in precision positioning equipment such as linear actuators, linear stages, rotation stages, goniometers, and mirror mounts. Other uses are in packaging machinery, and positioning of valve pilot stages for fluid control systems.

Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines and, more recently, in 3D printers.


Product description of Waterproof Stepper motor


  • The angular displacement of the stepping motor can be precise controlled by the number of electrical pulses.Angle accuracy can be controlled within ±0.09°without any feedback devices.
  • The material is selected from well-known manufacturers at home and abroad. The advantages are light weight, good heat dissipation performance, good thermal conductivity, die-casting, good plasticity, higher elongation than iron, low noise, good motion stability, the disadvantages are high price, low hardness
