Motors and Switches
250 mm Motor (Rail and Railless) – 36 VDC ±10%, 0.4 A typ, 1.2 A max.
Refer to 250 Millimeter Motor on page 4-5 and 250 Millimeter Railless Motor on page 4-6 for
the mechanical drawings.
1000 mm Motor (Rail and Railless) – 36 VDC ±10%, 1.5 A typ, 5.0 A max.
Refer to 1000 Millimeter Motor on page 4-3 and 1000 Millimeter Railless Motor on page 4-4
for the mechanical drawings.
125 mm R 90° Curve Motor (Rail and Railless) – 36 VDC ±10%, 0.4 A typ, 1.2 A max.
Refer to 125 Millimeter Radius 90° Curve on page 4-7 and 125 Millimeter Radius 90° Curve
Railless Motor on page 4-8 for the mechanical drawings.
Switch (Rail only) – 36 VDC ±10%, 1.5 A typ, 5.0 A max.
Refer to 90° Left Switch on page 4-9 and 90° Right Switch on page 4-10 for the mechanical
drawings.
NOTE: The motors and switches draw additional power when the vehicle (puck) is moving
or accelerating (refer to
Table 4-1 ). The amount of additional power drawn depends
on the vehicle’s velocity and acceleration, and the number of vehicles that may
accelerate at once. All power wiring must be capable of carrying the full load.
The propulsion power input (P1 V+ Propulsion) uses a PTC (positive temperature
coefficient) resistor to limit inrush current upon application of power. Limit cycling
of the propulsion power to three times or less per minute to allow the PTC to
cool-down. The PTC is only used for inrush current limiting and is bypassed in nor-
mal operation.
Providing a separate power source for the logic power allows the motors to be pro-
grammed and configured without enabling the propulsion power.
When using separate power sources for logic and propulsion power, the propulsion
power return should be tied to ground while the logic return can be left floating.
