Galil is excited to announce the release of the new D3643 drive, which is now available for the DMC-40x0 and DMC-41x3 series of motion controllers. Based on the existing D3640 drive which is designed to run 3-phase brushless motors, the D3643 is specifically designed to run brushed motors creating a more economical solution.

Linear Amplifier Benefits

Both the D3643 and D3640 are linear amplifiers which means there is no switching of the power transistors. This results in:

• Smooth, ripple-free motion
• High precision positioning
• Very little electromagnetic interference (EMI)

Specifications

The D3643 offers great performance for low inductance brushed motors as well as voice coil motors. Key specifications include:

Parameter	Value
Motor Channels	4 (independent)
Continuous Current	Up to 1 Amp per channel
Peak Current	Up to 2 Amps per channel
Voltage Range	15-40 VDC (single supply)

Considerations

All linear amplifiers will typically operate with far less efficiency than switching amplifiers resulting in higher heat generation. For applications requiring higher current, Galil has multiple pulse width modulation (PWM) amplifier options available. Galil can also create custom OEM solutions based on customer requirements.
