Galil is proud to introduce the 1200W AMP-43740, a new high power multi-axis servo drive with sinusoidal commutation. Based on Galil’s 600W AMP-43540, the new AMP-43740 is designed for applications with brushless motors that require greater continuous or peak current.

Internal Amplifier and Drive Comparison

The AMP-43740 contains four 1200W digital transconductance amplifiers for driving brushless motors with sinusoidal commutation, a 100% increase in power rating from the 600W AMP-43540. Each amplifier in the AMP-43740 can drive motors operating at up to 16 Amps continuous and 30 Amps peak at 20-80 VDC allowing the use of larger brushless motors to meet the needs of a wide variety of applications.
User-programmable gain settings, a switching and sampling frequency of 20kHz, and closed current loop bandwidth up to 2.5 kHz make that the AMP-43740 a high quality, easy to use amplifier. This amplifier also offers protection from over-voltage, under-voltage, over-current, short-circuit, and over temperature conditions.

With the AMP-43740 the user will benefit from the inherent characteristics of sinusoidal commutation resulting in continuous commutation with no unwanted torque ripple. As an additional benefit of sinusoidal commutation, Hall sensors are generally not required with Galil’s initialization commands.

The AMP-43740 four axis drive is available as an option for Galil’s DMC-500x0 EtherCAT Master and DMC-40x0 Accelera motion controllers. The drive resides inside the controller's enclosure in order to minimize space, cost, wiring, and setup time. Two 4-axis drives can be used witth an 8-axis controller for larger axis count applications.
