1.2 Degree 57mm Nema 23 Small Stepper Motor With Encoder

Advantages of 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.

What is waterproof motor, what requirements does motor waterproof have?

Most motors are not waterproof, in large part because they work in environments that do not require waterproofing, and waterproofing materials add costs that limit overall performance and are often of value only to specific applications, such as pumps and fluid handling, off-road vehicles and other applications where fluids may come into contact with motors.Because of water and solvent, motion control components are often exposed to the risk of corrosion and failure, and waterproof motor is the key component to solve the problem of water-induced motor failure.The motor industry has a standardized liquid protection measure, known as IP protection level, that electrical engineering and motor manufacturers need to meet the requirements of the application specification.
