# How fast can stepper motors turn?

## How fast can stepper motors turn?

1500 RPM
Taking into account that the motor Torque curve decreases with the increasing of the step frequency, modern stepper motors can reach rotation speeds of up to 1500 RPM. We get a displacement speed of 6000mm/min or 6 m/min if a screw of 4mm is run at 1500rpm.

## Can stepper motors be run continuously?

Stepper motors fall somewhere in between a regular DC motor and a servo motor. They have the advantage that they can be positioned accurately, moved forward or backwards one ‘step’ at a time, but they can also rotate continuously.

How is horsepower calculated?

The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.

Can you control stepper motor speed?

Stepper motors are motors that rotate in fixed intermittent steps. The movement of the second hand of an analog clock is a familiar example of this feature in practice. The angle and speed of rotation of stepper motors can be controlled simply and accurately by means of input pulses.

### Which is better stepper motor or DC motor?

The speed range of stepper motors is typically below 2000 RPM, as their torque decreases as speed increases….Table 1: Comparison of brushed motors vs. stepper motors.

Characteristics Brushed DC Motors Stepper Motors
Torque/speed characteristics High torque at low speeds Maximum torque at low speeds
Cost Low Low

### How accurate is a stepper motor?

Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3 to 5% of a step and this error is non-cumulative from one step to the next. Excellent response to starting/stopping/reversing. Very reliable since there are no contact brushes in the motor.

What’s the maximum speed I can get with a stepper motor?

Generally speaking the top speed of a stepper motor is approximately 1000rpm. The exact speeds that are possible depend on the specific motor being used and the controller being used with it.

What is the purpose of a stepper motor?

A stepper motor is an electrical device which divides the full rotation of the motor into individual parts called steps. Generally, these motors are brushless in order to facilitate a synchronous rotation and operate without the input of an external source on the gear itself.

#### How fast can a stepper motor run?

Modern stepper motors can reach rotation speeds of up to 1500 RPM, taking into consideration that the motor torque curve decreases considerably with the increasing of the step frequency.
