PhidgetBLDCMotorMBS.BrakingEnabled as Boolean   New in 25.0

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Phidgets	MBS Phidgets Plugin	25.0	✅ Yes	✅ Yes	✅ Yes	❌ No	Desktop, Console & Web

Whether braking is enabled.

This setting allows you to choose whether the motor will resist being turned when it is not being driven forward or reverse (Velocity = 0).

• Setting BrakingEnabled to FALSE corresponds to free-wheeling. This means: The motor will continue to rotate after the controller is no longer driving the motor (Velocity = 0), due to its momentum. The motor shaft will provide little resistance to being turned when it is stopped.
• Setting BrakingEnabled to TRUE will engage electrical braking of the DC motor. This means: The motor will stop more quickly if it is in motion when braking is requested. The motor shaft will resist rotation by outside forces.
• Braking will be added gradually, according to the Acceleration setting, once the motor controller's Velocity reaches 0.0
• Braking will be immediately stopped when a new (non-zero) TargetVelocity is set, and the motor will accelerate to the requested velocity.
• Braking mode is enabled by setting the Velocity to 0.0

Position values are calculated using Hall Effect sensors mounted on the motor, therefore, the resolution of position depends on the motor you are using.
Units for Position can be set by the user through the RescaleFactor. The RescaleFactor allows you to use more intuitive units such as rotations, or degrees. For more information on how to apply the RescaleFactor to your application, see your controller's User Guide.

PhidgetBLDCMotorMBS.StallVelocity as Double

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Phidgets	MBS Phidgets Plugin	22.1	✅ Yes	✅ Yes	✅ Yes	❌ No	Desktop, Console & Web

The stall velocity.

Before reading this description, it is important to note the difference between the units of StallVelocity and Velocity.

• Velocity is a number between -1 and 1 with units of 'duty cycle'. It simply represents the average voltage across the motor.
• StallVelocity represents a real velocity (e.g. m/s, RPM, etc.) and the units are determined by the RescaleFactor. With a RescaleFactor of 1, the default units would be in commutations per second.

If the load on your motor is large, your motor may begin rotating more slowly, or even fully stall. Depending on the voltage across your motor, this may result in a large amount of current through both the controller and the motor. In order to prevent damage in these situations, you can use the StallVelocity property.

The StallVelocity should be set to the lowest velocity you would expect from your motor. The controller will then monitor the motor's velocity, as well as the Velocity, and prevent a 'dangerous stall' from occuring. If the controller detects a dangerous stall, it will immediately reduce the Velocity (i.e. average voltage) to 0 and an error will be reported to your program.

• A 'dangerous stall' will occur faster when the Velocity is higher (i.e. when the average voltage across the motor is higher)
• A 'dangerous stall' will occur faster as (StallVelocity - motor velocity) becomes larger .

Setting StallVelocity to 0 will turn off stall protection functionality.

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Phidgets	MBS Phidgets Plugin	22.1	✅ Yes	✅ Yes	✅ Yes	❌ No	Desktop, Console & Web

The braking value.

When a motor is not being actively driven forward or reverse, you can choose if the motor will be allowed to freely turn, or will resist being turned.
A low TargetBrakingStrength value corresponds to free wheeling, this will have the following effects:
The motor will continue to rotate after the controller is no longer driving the motor (i.e. Velocity is 0), due to inertia.
The motor shaft will provide little resistance to being turned when it is stopped.
A higher TargetBrakingStrength value will resist being turned, this will have the following effects:
The motor will more stop more quickly if it is in motion and braking has been requested. It will fight against the rotation of the shaft.
Braking mode is enabled by setting the Velocity to MinVelocity

PhidgetBLDCMotorMBS.TargetVelocity as Double

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Phidgets	MBS Phidgets Plugin	22.1	✅ Yes	✅ Yes	✅ Yes	❌ No	Desktop, Console & Web

The average voltage across the motor is based on the TargetVelocity value.

At a constant load, increasing the target velocity will increase the speed of the motor.
TargetVelocity is bounded by -1×MaxVelocity and MaxVelocity, where a sign change (±) is indicitave of a direction change.
Setting TargetVelocity to MinVelocity will stop the motor. See TargetBrakingStrength for more information on stopping the motor.
The units of TargetVelocity and Acceleration refer to 'duty cycle'. This is because the controller must rapidly switch the power on/off (i.e. change the duty cycle) in order to manipulate the voltage across the motor.
