The PMG500 rectifier is required when utilizing the larger 800 Nm (590 lb-ft)
- and 1200 Nm (885 lb-ft) twin-rotor brakes. In order to prevent rapid wear,
NORD recommends using the PMG500 rectifier to “overexcite” the brake
during its release. The brake coil should be sized utilizing the PMG rectifier
like a half-wave rectifier.
