No, stay on site OK. Check at least two of them. In order to be able to benefit from the advantages of field-oriented control even in price sensitive applications, Nanotec has developed a sensorless control for stepper motors that uses a virtual encoder in the controller to determine the current position and speed of the rotor. Available in three lengths. The simplest sensorless control is to directly measure the back-EMF while a coil is de-energized in the commutation cycle. Another important aspect regarding the practical use of a sensorless controller is the identification of the parameters of the model. Our video shows how stepper motors are operated in closed loop mode with sensorless control and no encoder.

Our controllers are offered with various fieldbus interfaces and have digital and analog inputs as well as digital outputs.
Ideal for precise positioning and For this reason, demanding applications now rely on systems that, using an “observer”, reconstruct values that cannot be measured directly, such as the speed or back-EMF, from other values that are measured by the current controller. In addition to our two sales offices in the US, Nanotec employs a nationwide network of sales partners who will provide expert technical support to your company.

Open the attribute in the Filter. Click on Reset settings. The heart of closed loop technology is a power-adjusted current control and control signal feedback.
The desired attributes for each motor wil be displayed by clicking on the boxes on the right of the legend. In the legend table you can then see the speed values. Dear Customer, If you would like to request a quotation, please log in or register.
BLDC controllers frequently require a large number of motor-dependent parameters that are often not specified on the data sheets but need to be determined with considerable effort. Different motors can have identical torque curves.
Please wait while productfinder is loading Dear Customer, If you would like to request a quotation, please log in or register. Current per Winding naanotec. Solid torque curves represent thrust, and dashed torque curves represent output power. These stepper motors are controlled in exactly the same way as servo motors: However, its accuracy decreases with the speed, and the achievable torque drops as well. Available in various lengths and versions.
The desired attributes for each motor wil be displayed by clicking on the boxes on the right of the legend. Current per Winding 5.
How to use the product finder Product Finder Instructions. The Results will adjust themselves automatically to the values you have set. Enter a search word or scroll through the list to find the desired attribute.
Depending on the motor type, the speed and positioning information is obtained at a lower speed of between 25 and rpm with an accuracy comparable to that of an optical encoder with or increments.
Filter the matching motors using the attributes “Torque” and “Thrust”. Hanotec are nanoetc for closed loop control with encoder, sensorless control or for control via Hall sensors and offer precise position, speed and torque control.
Thus, correct estimates can be obtained for the values that are not actually measured, nanorec as the speed. At high speeds, in contrast, the sensorless system actually works better than a rotary encoder, which always exhibits a runout tolerance that leads to a sinusoidal angular error.
It is possible to switch automatically to open loop mode for lower speeds and for positioning purposes. If you would like to request a quotation, please log in or register.
You can select up to 6 products for a torque curve comparison. Moreover, the positioning accuracy of stepper motors without an encoder is usually sufficient in these applications.
