Servo drives with sinusoidal commutation, less torque ripple

Galil Motion Control has added two multi-axis servo drives that perform sinusoidal commutation, which minimize torque ripple.

Galil Motion Control has added two multi-axis servo drives that perform sinusoidal commutation: the AMP-43540 which contains four 600Watt servo drives and the AMP-43640 which contains four 20 Watt servo drives. Both models are sinusoidally commutated which minimizes torque ripple compared to drives using trapezoidal commutation. This is especially important for applications using low friction linear motors.

The new AMP-43540 and AMP-43640 4-axis drives are available as options for Galil’s DMC-40x0 Accelera and DMC-41x3 Econo motion controllers with Ethernet. Designed to minimize space, cost and wiring, the drives reside directly inside the controller enclosure. The packaging of the 4-axis drive inside the motion controller enclosure saves space compared to using external drives. The DMC-4040 4-axis controller and drive package dimensions are 8.1 x 7.3 x 1.7-inch. Two 4-axis drives can also be installed inside the DMC-4080 8-axis controller package which measures 11.5 x 7.3 x 1.7-in.

The new AMP-43540 contains four 600Watt fully digital, transconductance amplifiers for driving brushless motors with sinusoidal commutation. Each amplifier drives motors operating at up to 8 Amps continuous, 15 Amps peak, 20-80 V dc. The gain settings of the amplifier are user-programmable at 0.4, 0.8 and 1.6 Amp/Volt. 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 new AMP-43640 contains four 20Watt linear, transconductance amplifiers for driving brushless motors with sinusoidal commutation. Each amplifier drives motors operating at up to 1 Amp peak, 15-30 V dc with a gain setting of 0.1 Amp/Volt.

When using the AMP-43540 and AMP-43640 sinusoidal drives, hall sensors are not required for brushless motor commutation. Galil provides commands for initialization of the motor using the encoder feedback.
