Controllo di velocità

In the configuration for brushless motors with hall sensors, the motors are operated with speed control, whereby the signals from the Hall sensors are used for commutation and determination of the actual speed for the Speed Controllers.

In this combination of BL motor and speed controller, no hall sensors are used. Instead, the back-EMF of the motor is used for commutation and speed control.

This configuration of the Speed Controllers can only be selected in combination with the appropriate hardware. In this configuration, the encoder outputs an absolute position. This is used for commutation as well as for speed control. Due to the high resolution of the encoder, (absolute encoders) can achieve low speeds in this mode.

In this configuration, the motors, in combination with a speed controller, are operated speed-controlled and offer the additional brake and enable inputs. Through these inputs easier connection of the control to e.g. PLCs or safety circuits is possible.

In the configuration, consisting of DC motors with encoder and Speed Controller, the motors are operated with speed control by means of an incremental encoder. The incremental encoder is needed here as an actual value encoder for speed control.

In a DC motors configuration without encoder, the speed-controlled motors are operated without a sensor with the use of a Speed Controller. Depending on the given load condition, either the back electromotive force (EMF) or IxR compensation is used for speed actual value acquisition. Matching to the respective motor type is required for this type of speed control.
