1 INTRODUCTION

This publication covers operation, installation and maintenance instructions for

the ACT2000 Actuators manufactured by Precision Engine Controls Corporation.

1.1 Application

The ACT2000 All-Electric Actuator is designed to meet general industrial motion

control requirements for high temperature hazardous locations. Typical

applications include gas turbine guide vane and valve motion control.

1.2 Mounting Provisions

The ACT2000 can be pin or flange mounted. Figure 1-1 shows a pin-mounted

actuator. Figure 1-2 shows a flange-mounted actuator. Other configurations can

be provided. Please consult Precision Engine Controls Corporation.

Figure 1-1 ACT2000-590P Pin Mounted Figure 1-2 ACT2000-200F Flange Mounted

The pin-mounted ACT2000 configuration includes a stainless steel machined

clevis. The clevis is fully rotational to allow variable angular indexing as required

for installation. The extension rod provides a female thread for user supplied end

attachments. A spherical rod end bearing attachment is preferred.

The ACT2000 contains a brushless direct current (DC) motor-driven linear

actuator with on-board digital motor control electronics. The primary actuator

components are described in the balance of this section.

1.3 Main Housing Assembly

The main housing assembly contains a main housing, motor cover, extension rod

bearing, and associated seals. See Figure 1-3. The main housing assembly is the

primary structural system component and supports all the bearings, motor control

electronics, motor cover, and mountings, which forms the explosion-proof

containment.

In order to provide main bearing thermal dimensional stability, the housing is fitted

with a stainless steel liner. The liner is permanently installed into the aluminum

main housing. A retaining ring is included for redundant retention.

The main housing contains rigid mechanical stops to prevent extension rod

travel beyond the design specification.

1.4 Brushless DC Motor Assembly

A brushless DC motor powers the ACT2000 linear drive mechanism. The DC

motor contains a stator and rotor. See Figure 1-3

Motor Stator

The motor stator is attached to the main housing by a pre-loaded wave spring

and screws. Thermistors are embedded in the stator windings to monitor winding

temperatures. The motor electrical power and thermistor wires pass from the

motor through a conduit into the electronics housing.

Motor Rotor

The motor rotor is locked to the ball screw shaft via a straight key. The motor rotor

contains powerful magnets that align with the energized stator windings thereby

creating torque and shaft rotation.

1.5 Motor Control Electronics

The motor control electronics (MCE) are contained within the main housing

electronics enclosure. The MCE includes harnesses, heat sink, digital and driver

component assemblies (CA).

The MCE electronics communicate with the user’s controller through analog and

serial interfaces. The MCE controls the brushless DC motor, to position the

actuator based on position feedback from the resolver.

Note: The digital board analog and discrete interfaces are electrically

isolated. The MCE serial interface is NOT electrically isolated.

1.6 Resolver Assembly

A Brushless, non-contacting resolver is the primary ACT2000 feedback sensor.

A sinusoidal feedback signal is provided from the resolver to the motor control

electronics. A sinusoidal signal from the MCE provides the resolver excitation.

The resolver includes a stator and rotor. See Figure 1-3

Resolver Stator

The resolver stator is clamped to the main housing between the main bearing

retaining nut and resolver retainer. The resolver stator angular position relative to

the rotor is adjustable. Electrical wires from the resolver are reeled in the resolver

adapter to allow rotation. The resolver wires, along with the motor and thermistor

leads, are routed through a conduit into the electronics housing.

Resolver Rotor

The resolver rotor is mounted by a key to a ball screw shaft. As the rotor rotates,

the stator transformer output signal provides shaft rotation information to the

MCE.

1.7 Linear Drive Mechanism

The Linear Drive Mechanism converts the rotary motion of the Motor Assembly to

linear actuator motion. The core of the mechanical drive system is the linear ball

screw drive containing a screw shaft, ball bearing fitted nut, extension rod and

main duplex thrust bearings.

Screw Shaft

The thrust bearings, motor rotor, motor end bearing, and resolver rotor are

mounted directly to the screw shaft. A ball bearing track is machined into the

screw shaft.

Ball Nut

As the screw shaft rotates, the ball nut translates in an axial direction depending

on shaft rotation.

Extension Rod and Bearings

The extension rod is threaded on the ball nut. As the ball nut translates, the

extension rod moves in and out of the ACT2000 main housing.

The extension rod support bearing is provided for lateral support. Thrust and

radial loads are transferred from the extension rod through the ball nut to the main

preloaded duplex thrust bearings. The thrust bearings transfer the loads to the

main housing by the main bearing and shaft retaining nuts.

A motor end bearing is provided for additional shaft radial stability. The resolver

rotor, motor rotor, motor bearing, and spacers are stacked on the ball screw shaft

and retained by a single nut. This arrangement prevents actuator axial loads from

passing through the resolver rotor and motor rotor.

1.8 Power and Digital Harness

A four-wire electrical harness with two (2) meter free leads provides the ACT2000

electrical power inputs. The four-wire harness allows for redundant electrical

inputs.

A seventeen-wire electrical harness with ninety (90) inch free leads provides

ACT2000 signal interface. Contained within this seventeen-wire harness are

discrete commands, analog commands, feedback, and serial interface wires.
