Power Supply
3.2.1
Power supply
(only MAC050 to 141)
The power supply must be connected to the terminals 48V and GND.
The supply voltage can be in the range 12VDC up to 48VDC; however the maximum
speed of the motor (4000 RPM) is based on 48VDC. A lower voltage will decrease speed
performance.
This curve below shows the relationship between voltage and recommended speed.
If a supply voltage lower than 48VDC is used, it will not influence the motor torque unless
the corresponding speed at this voltage is overridden. The MAC motor continuously
measures the actual supply voltage and optimises the current control filter. This feature
ensures that the motor always produces full torque within the safe area of operation.
3.2.2
Power supply grounding
(only MAC050 to 141)
No additional grounding/earthing of the motor is necessary since the complete motor
housing is connected directly to pin 2 of the Power Supply connector.
The overall earthing of the system must be done at a central point close to the power
supply.

A 4700µF/50V capacitor
in the power supply out-
put is recommended.

The distance between the
MAC motor and the
capacitor must be less
than 3 metres otherwise
the peak performance of
the motor is reduced.
