The moderns stepper motors can reach rotation speed of 1500 RPM. It must be considered that the motor torque curve decrease considerably with the increasing of the step frequency. If we take a screw of 4 mm and we run it at 1500 RPM we obtain a displacement speed of 1500*4mm=6000mm/min or 6 m/min. In practice the stepper motors runs at max 600 RPM because the torque decrease above that values.

Resonance is an unstable condition when running a step motor. Resonance usually occurs between 2-4 rev/sec and can be alleviated in most situations by putting a load on the motor, changing from full stepping to half or microstepping, or increasing your acceleration through the resonance zone.

A stepper motor controller, more generally called Motion controller, is a system that control the rotation of motors (stepper, brushless, sevomotors) with the purpose of moving a mechanical (axis in CNC machines) to a determined position. Motion controller must not be confused with motors drivers that are the power part of a positioning system. The firsts are those systems based on a PC that give the signals for the motors through the parallel port. See similar questions...

The resolution of an axis system moved by stepper motors depend uniquely by the mechanical. The stepper motors have generally a 1.8? step angle so they make a complete rotation with 200 step when drive at full step. For example, if the motor drive a screw of 4 mm., a complete turn will make a displacement of 4 mm. and so the resolution will be 4/200 mm= 0.02 mm. Obtaining a mechanical with backslash less than this is very difficult. See similar questions...

I like servo motors because: they are quiet, more power at high rpms, machines can move at least three times faster than steppers, rotational movement is smooth instead of jerky. See similar questions...

Servos produce more torque at any speed than comparable stepper motors. This can be up to 400% more torque for equally rated motors. Servos are under closed-loop control via their encoders, allowing additional power to be sent to the motor when resistance is encountered. Steppers, on the other hand, will simply stall and lose their position relative to the control -- resulting in improperly machined parts. See similar questions...

Our tools and equipment perform at speeds of up to 2,300 ft/min. Please keep in mind that this depends very much on the material and the hole size. With a diameter of 0.040", for example, a maximum speed of approx. 250 ft/min can be expected. See similar questions...

Most stepper motors have class B insulation which is rated at 130 degrees C. Motor case temperatures of 90 degrees C will not cause thermal breakdowns. Motors should be mounted where operators cannot come into contact with the motor case. See similar questions...

For safety reasons, an engineer wants to know how long it takes for a drive's DC Bus to dissipate once the main power is disconnected. In theory, the drive's bus will never dissipate completely due to the logarithmic behavior of the DC Bus capacitor but in actuality we can do the calculations based on a final voltage that approaches zero volts. The minimum amount of time required before the drive dissipates the voltage can be worked out as follows: Motor Resistance (D062M) = Rm = 3. See similar questions...

If you are only operating one stepper motor using any of our boards which have the GenStepper firmware installed, and if that motor does not require use of the Double Current Mode of operation, then you may operate up to 2 relays at the same time as you operate the stepper motor. The manual is in Adobe Acrobat format, and is available from our downloads page here. See similar questions...

The 90 Volt DC motor offers far more torque than the 1/2 HP AC/DC motors we used to use. (It is also much smoother and quieter.) The electronic speed control adjusts automatically for any voltage world wide from 100 to 240 volts, 50 or 60 Hz. (For more details, see complete motor specifications and torque curve chart in the file on Sherline tool dimensions.) An electronic circuit in the new speed control unit also compensates for load, keeping the RPM more constant during cuts. See similar questions...

The Dimming Module is designed to control both lamp and motor loads. Each leg will control up to a 1/8 HP variable-speed motor load, and with ganging up to a 1 HP motor may be controlled. See similar questions...

Depending on where you live, our state-of-the-network allows download speeds of 2Mb, up to 16Mb. all depending on how far you are from the exchange the further away you are the less speed you get See similar questions...

Our Segways are equipped with Nickle Metal Hydride (NiMH) batteries good for about 12 miles on a full charge. New model Segways now come equipped with Lithium-Ion batteries that will get you twice that far. Average charge time is roughly 6 hours, but with the built in charge management package, you can just plug it in and forget it. No memory developing, no overcharging, just a simple wall outlet is all you need. As for speed, the segway has three different pre-programmed settings. See similar questions...

The recommended maximum stroking speed for NITRO-SPRINGS is 35 metres/minute; it must be remembered that this is not the cyclic speed of the press. We recommend a maximum stroke rate of sixty cycles per minute. See similar questions...

A number of factors affect the speed and quality of ADSL transmission. Among the causes of poor transmission speed are: The distance and line quality from the NTT central office to your premises. It is a fact that speed generally declines the farther you are from the central office. See similar questions...

The stop's maximum speed is approximately 20 inches per second. If moved faster, the display may require re-calibration. See similar questions...

The factor that limits operation is the speed at which measurement data can be transmitted over the network that connects the sensors to the Data Logger. This is limited by the speed of the network the ability of the Data Logger to read and store it. Each sensor node has its own microprocessor to control the measurement cycle, provide automatic range changing / diagnostics and network interface. This does not have any practical limitations.
