Preface
HR8 Motor User Manual I
CE Compliance
The LN-2000 family drivers and motors complies to the following
directive:
Safety : IEC 61010-1:1990
EMC : 89/336/EEC as amended by 92/31/EEC and 93/68/EEC
Harmonized Standards to which conformity is declared:
EN 50081- 2:1993/EN 55011:1991
Generic Emission Standards Class A for radiated emission and
Class B for conducted emission.
EN 50082- 2:1995 Generic Immunity Standard
NOTE: UHV motors are designed for convenient interface to the
UHV setup. The motors are therefore supplied with three open
electrical leads. Whereas standard motors comply with CE
regulations and the UHV motors have the same internal design as
standard motors, the UHV motors are supplied as components and
CE conformity in both EMI and Safety must be implemented as part
of the UHV system design.

Warnings and Cautions
WARNINGS
Do not remove the cover of the motor or disassemble its
connector. High voltage inside.
Be sure to ground the motor to the electrical network ground
(according to the following instructions) before operating the
motor.
CAUTIONS
! Arrows on motor indicate direction of motion. Align
accordingly.
! Do not set power-on unless motor is mounted and preloaded!
! Do not immerse the motor in any liquid or cleaning agent.
! Use only a clean cloth to wipe the motor.
! Be sure that the motor, and specifically the 'finger tips', are
not subjected to mechanical shocks.
! Be sure that the distance of the motor to the plate enables
the motor finger tip to contact the driving plate, otherwise the
motor might be damaged during operation.
! The mounting base and the method used for mounting
should be designed for maximum mechanical rigidity and
stiffness.
! Reducing the length of the supplied motor cable may damage
the motor. Do not attempt to shorten the cable without prior
confirmation from Nanomotion.
!
Extending the motor cable will not damage the motor,
however it will affect its performance.

1. Introduction
1.1 About the Motor
The HR8 motors are high precision ceramic motors belonging to
the Nanomotion LN2000 product line. Designed and manufactured
by Nanomotion, Ltd., the HR8 motors, combine unlimited stroke
with high resolution in compact dimensions. Among its applications
are microscopy, precision motion, robotics, etc.
The motors provide a linear response to the input voltage. The
operation of the motor and driver resembles that of a DC-motor
driven by a voltage amplifier.
The specifications described in this chapter apply only to the motor
driven by the AC-1 Driver Card and the AB-1 driver box. Minor
differences may result if NCD Controller Driver, DC-12 Driver Card,
or DB-121/122 Driver Box are used.
1.2 Vacuum Motors
Applications of the Nanomotion motors for vacuum and
high-vacuum environments include wafer inspection and metrology,
scanning stages and lithography. The HR8-V and HR8-U motors
are constructed of materials that have been selected and designed
for high vacuum compatibility.
Introduction
HR8 Motor User Manual 1-2
1.3 HR8 System Parts
A complete set for a single axis will comprise of the following:
a) HR8 Motor
b) Ceramic Driving Plate for linear applications or Ceramic Driving
Ring/Disk for rotary applications (see section 2.2.1)
c) LC-Box (Tank Circuit)
d) One of the following drivers:
! AC-1 Driver Card
! AB1
! DC-12 Driver Card
! DB-121 or 122 Driver Box
! NCD Driver Controller Box
NOTE: For the first 4 driver options, use a standard off-the-shelf
DC Controller with a servo rate of 10KHz or more. You may
consult Nanomotion for the recommended controller.
The option for NCD Driver Controller Box consists of a driver and
an integrated controller.
1.4 Handling
CAUTIONS
Do not set power-on unless the motor is mounted and preloaded!
Do not immerse the motor in any solvent or cleaning agent.
Use only a clean cloth to wipe the motor.
Be sure that the motor, and specifically the 'finger tips', are not
subjected to mechanical shocks.
1.5 Installation and Servicing
It is recommended to follow the installation instructions in this
guide, when mounting and installing the motor. The HR8 does not
contain any user-serviceable parts.

2. Preparation and Installation
2.1 Preparation
For optimal motor performance, it is recommended to use the
Ceramic driving plate provided by Nanomotion. These driving
plates have been specifically designed to work with Nanomotion
motors.
Substituting this plate with any other material might reduce motor
performance or damage the motor.
NOTE: The instructions given in this section refer to the standard
ceramic driving plates provided by Nanomotion. Nanomotion can
not guarantee performance attained by plates purchased from
other sources.

HR8 Motor User Manual 2-2
2.1.1 Mounting Base
Prepare the base as described in Section 3.3.3 - Mounting Base
Dimensions. The base should be positioned perpendicular to the
Ceramic driving plate that is bonded to the stage.
If necessary, refer to the schematic for motor dimensions.
CAUTION: The mounting base and the method used for mounting
should be designed for maximum mechanical rigidity and stiffness.

of the Ceramic driving plate.
For driving plate dimensions please refer to the price list.
The four screws securing the motor to the mounting surface will be
inserted from its underside. Any protrusion of the screws might
interfere with motion on another axis.
