Configuration
DC motor Variable speed control
module is an Original Manufacturing Engineering (OEM)
industrial and commercial rated high performance, high
efficiency Direct current (DC) speed control.
The PIVOT P2 drive is a reliable and cost-effective solution
for controlling your permanent magnet or shunt-wound DC motors
in variable-speed applications. It uses SCR's to provide
full-wave rectification of the AC line input. This dual voltage
drive operates using 110VAC/115VAC/120VAC, 50/60Hz, to operate 90VDC SCR
brush-type Fractional HP (FHP) and HP motors from 1/8 to 2 HP.
The DC Variable Speed Motor
Control is a feature rich electronic interface board module
designed to control 90V DC
permanent magnet (PM) or Shunt-Wound (SHWD) motor locally via
potentiometer and/or switch. The output average voltage is a linear function of the
potentiometer rotation. If used properly, it will
eliminate the need for expensive boards and instruments, which
would otherwise be required to carry out the same control tasks.
Depending on model, the control
can drive a 90V DC PM motor at verity of
Horse Power (HP), while powered by standard
120VAC/60HZ. Therefore, it can be powered by
US standard power source. It
provides smooth control operation with high efficiency in a
compact form.
The EID-PIVOT-P2 driver used in applications require
constant torque throughout the application with good speed
regulation such as conveyors, extruders, winders, printing
presses, food process equipment and metering pumps controlled by
90VDC Permanent Magnet (PM)
Horse Power Motor.
The board offers the features
needed for professional high current DC motor control. The board
also include built-in on board protection
fuses, and transient and surge suppression.
The PIVOT P2 drive constructed with solid‑state, full wave
design with Integrated circuitry using state‑of‑the‑art
electronics ‑ ensures a fast, accurate response. Both AC input
lines fused ‑ maximizes drive protection. Additionally on board
start/stop control relays ‑ prevents restart of drive after
power interruption. Furthermore controlled acceleration and
deceleration of 0 to 10 seconds ‑ provides both, soft
motor starting and stopping.
Mounting is easy via four 0.156"
mounting holes using 6-32 screws and wire (optional) via
convenient conventional industrial standards 90 degrees (.187) high current Quick-Fit terminals.
