Motor Driven Coaxial Phase Shifters

DC Motor Drives For Phase Shifters

ATM manufactures a variety of DC motor drives for phase shifters that allow phase changes to be performed remotely. 

Our complete phase shifter line includes phaseshifters with 30, 40, 60, 90, 180 and 360 degree phase shift with standard mechanical adjustments, digital counting dials and direct reading dials.

Any of ATM's phase shifters can be used with the motor drive modules on this page.

For more information on phase shifters or DC driven phase shifters, please call us and discuss your needs with one of our design engineers.

  • ATM's motor driven phase shifters utilize DC motors with integrated, long life gear reductions ideal for High Reliability applications.
  • The unit will operate with a set DC voltage between 18-30VDC, commonly found in most systems or by a separate DC power supply. Motor speed will vary based on Voltage used. Maximum running current is 250mA & 600mA max starting.
  • To prevent motor damage, micro switches are used to stop the motor at the minimum and maximum travel positions
  • Units are provided with a 9 pin D Sub Male connector allowing for control voltage, end point indication if desired, and follower potentiometer. See connector pin-out details.
  • These devices are best controlled by an external Double-Pole/Double-Throw (DPDT) switch or for better control use the optional ATM External Control Module.
  • Any one of ATM's Phase Shifters can be mounted to a motor drive.

 

Interface - Motor Driven Phase Shifters

1. Motor Control Voltage
Pins 2 and 7 of the nine pin D Sub male connector will have fixed DC voltage between 18-30 volts applied.  To increase phase pin 2 is (+) and pin 7 is (-).  To reverse the direction 2 is (-) and 7 is (+).  In both directions a stop is provided by means of Micro switches.

2. End Point Indicator *
The switch is also used to provide end point indication by means of pins 1 and 6 developing a voltage when the device has reached the maximum limit, (for 2+ and 7-). Pins will 3 and 8 will develop a voltage when a minimum limit is met. (for 2- and 7+). The developing voltage is equal to supply voltage used.

3. Follower Potentiometer **
A 10K Pot with an output proportional to the position of the motor drive mechanism is available at pins 4, 5, and 9.

* When ordering a Motor Driven Phase Shifter, you will need to create the actual model number, based on the specific phase shifter of you choosing by adding the suffix -28 at the end of the model number.
See our Phase Shifter page to find the  30°, 60°, 90°, 180°, or 360° model you wish to start with.
Example:   P/N P1604 becomes P1604-28 when ordering as a motor driven unit.
Any one of ATM's Phase Shifters can be mounted to a motor drive.

 

Optional External Control Module
An External Drive Control Module, part number MCM-001 shown at right, is available for the motor drive as an optional accessory. It includes:
 
1.  Crisp tactile switches to control drive.
2.  Max/Min position indicator lights.
3.  Follower potentiometer terminals.
4.  Self-switching power supply with input of 120 VAC - 240VAC.*     
5.  6 Ft, 9 pin cable to interconnect the control box to the motor driven device.  

*If supplied power source is not used, an input of 18-30 VDC through the 9 pin connector may be substituted.
