Drive
Indestructible 3-phase drive with a cage motor in conformance with stan-
dards.
External motor control for power supply to the drive.
The following versions are available:
MOC E motor control
fixed rotational speed of 4,500 rpm at 50 Hz mains supply
reasonably priced version, recommended for test speeds at which a ro-
tational speed of 4,5000 rpm is sufficient for gapless testing (cf. Test
head selection table, page 2-6)
MOC S/SB motor control
rotational speed switchable 4,500 or 9,000 rpm,
with or without electrical breaking
minimized bearing wear through adaptation of rotational speed to test
speed
suitable for applications with changing test speeds
Both motor controls supply the required voltages and currents and contain
the necessary switching and safety devices (contactors, motor protection
switches, protective circuits).
The drive motor is connected directly using a Harting plug connector.
