Galil Motion Control is announcing two multi-axis servo drives that perform sinusoidal commutation: the AMP-43540 containing four 600W servo drives and the AMP-43640 containing four 20W servo drives.

Both models are sinusoidally commutated, which minimises torque ripple compared to drives using trapezoidal commutation.

According to Galil, this is especially important for applications using low-friction linear motors.

The AMP-43540 and AMP-43640 four-axis drives are available as options for Galil’s DMC-40×0 Accelera and DMC-41×3 Econo motion controllers with Ethernet.

Designed to minimise space, cost and wiring, the drives reside directly inside the controller enclosure.

The packaging of the four-axis drive inside the motion controller enclosure saves space compared to using external drives.

The DMC-4040 four-axis controller and drive package dimensions are 8.1 x 7.3 x 1.7in.

Two four-axis drives can also be installed inside the DMC-4080 eight-axis controller package that measures 11.5 x 7.3 x 1.7in.

The new AMP-43540 contains four 600W fully digital, transconductance amplifiers for driving brushless motors with sinusoidal commutation.

Each amplifier drives motors operating at up to 8A continuous, 15A peak or 20-80VDC.

The gain settings of the amplifier are user-programmable at 0.4, 0.8 and 1.6 A/V.

Both the switching and sampling frequencies are 33 kHz.

The amplifier offers protection for over voltage, under voltage, over current, short circuit and over temperature.

A shunt regulator option is available.

The US list price of the AMP-43540 four-axis 600W drive is $1,000 in single quantity and $600 in 100 quantities.

The AMP-43640 contains four 20W linear, transconductance amplifiers for driving brushless motors with sinusoidal commutation.

Each amplifier drives motors operating at up to 1A peak, 15-30VDC with a gain setting of 0.1A/V.

The US list price of the AMP-43640 four-axis 20W drive is $600 in single quantity and $350 in 100 quantities.

When using the AMP-43540 and AMP-43640 sinusoidal drives, hall sensors are not required for brushless motor commutation.

Galil provides commands for initialisation of the motor using the encoder feedback.

The AMP-43540 and AMP-43640 are available for immediate delivery.
