FAULHABER Speed Controllers are specifically designed to get the most out of FAULHABER DC and BL motors. They are compact, easy to operate and offer precise as well as efficient speed control. The individual speed control can be set easily via a computer and the free "FAULHABER Motion Manager" software.
Speed Control from FAULHABER are highly dynamic speed controllers for controlling:
Depending on the size and delivery state, different motor and sensor combinations can be operated on the Speed Controller. The different sizes as well as the flexible connection possibilities open a wide range of applications in areas such as laboratory technology and equipment manufacturing, automation technology, handling and tooling devices and machine tools or pumps.
Speed Controllers from FAULHABER can be adapted to the given application via the FAULHABER Motion Manager software. With the Speed Controllers, the operating mode, the controller parameters as well as the type and scaling of the set-point specification can be configured. A USB programming adapter is used for configuring the Speed Controllers.
The motor speed is controlled via a PI controller with variable parameters. Depending on the version, the speed in the speed controller is determined via the connected sensor system or sensorless from the motor current. Setpoint specification can be performed using an analogue value or a PWM signal. The direction of rotation is reversed by means of a separate switching input. Furthermore, it is possible to read out the speed signal of the Speed Controller via the frequency output. The motors can optionally also be operated as a voltage controller or in fixed speed mode.
FAULHABER Speed Controllers determine the temperature of the motor winding from the motor load characteristic. Dynamically, a peak current which is typically 2 times larger than the continuous current is available as a result. With a continuously higher load, the current is limited to the set continuous current. In the case of frequent reversing operation with large connected masses, it is recommended to use a Motion Controller.
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.
