Can stepper motors run continuously?


Can stepper motors run continuously?

If by “run” you mean rotating, then yes. But that’s true generally for all motors, they are designed to do that.

What most motors can’t do is to stop while under power. Try to hold down the shaft of a DC or AC motor while it’s still connected to the power supply - it will likely break (burn).

Stepper motors, on the other hand, are usually designed to survive even that. Their job is to make a discrete (ie. fix angle) step and then stay there; step again, stay there, etc.

If you make it stay in one position for very small time before stepping again, then it will seem to be continuously rotating. (By the way, their design is essentially the same as an AC synchronous motor, just driven by square wave instead of sine, though something resembling a sine is also sometimes used with steppers for a more smooth running.)

Stepper motors will have a higher current/power consumption and dissipation when stopped and if designed poorly it may overheat in time. For this reason the current of the motor is often decreased (eg. by PWM) when it is in a holding position for longer time.

(The reason is that when a motor’s rotating, part of its input electrical power is converted to mechanical power (rotation). When it’s stopped, all input power is converted to heat on the coils inside.)

Cloudray Stepper Motor Series has set the standard for quality, reliability, and durability in stepping motors. The precision of our Torque Power motors is matched only by the dependability of their performance. All Torque Power motors are bi-directional and totally enclosed with permanently lubricated ball bearings for long-lasting, smooth operation.

High Torque, High Precision and Long life is Cloudray's core advantage

Low vibration,Low heating, No loss of step
Fast Response,Better Acceleration Performance
Thanks to a robust design they can be selected for the harshest environments. Precise, open-loop, speed and position control can be achieved with the application of full step, half step, or microstepping electronics.

Higher Resolution,Avoidance of Resonance Regions
Stepping angle is adjustable( rang in 18°±5%), 0.9 °stepper motor's stepping angle is smaller, fineness is higher and positioning is more accurate.Avoiding vibration,runs more smoothly and gets lower noise.
Sturdy structure, extremely long life
High quality materials including bearings and shaft made in Japan
Robust assembly, high speed range, and exceptional performance in even the harshest environments make Cloudray Stepper Motors the perfect solution for demanding positioning applications.
Short length and light weight allow them to be used in highly integrated systems
