A direct-drive motor with advanced
features only available from NSK

With advanced features, including high torque, high resolution, maximum rotational speed of 10 [s–1] (PS Series),
high rigidity and compactness, the Megatorque Motor complies with CE mark (PS/PN Series), UL standards (PS/
PN Series), and the EU RoHS directive. These innovative direct-drive motors are extremely accurate, light-weight,
and boost the productivity of various devices.

High resolution 2 621 440Resolution of position sensor
[count/revolution]
The Megatorque Motor’s absolute position sensor is capable of a high
resolution of 2 621 440 [count/revolution] and repeatability of ±2 [arc-sec].
It requires no homing operations and facilitates the development of highly
accurate devices.

Shortened positioning time 1/5Settling time
Less than
A new servo algorithm shortens settling time to less than one-fifth
of conventional NSK motors. Shortened positioning time boosts the
productivity of various devices.

High torque twiceForce density as
much
The optimal magnetic field design gives it more than twice as much force More
density as conventional NSK motors. A maximum of 50% increase in motor than
torque increases productivity during high acceleration/deceleration drives.

Compact motor 35Height φ100Outer diameter
[mm] [mm]
NSK’s advanced design technology has produced two unique motor (PN2) (PS1)
series: the low profile PN Series (height of PN2: 35 [mm]) and the light and
compact PS Series (outer diameter of PS1: φ100 [mm]). With IP66M
brake compliant
Extensive lineup

The product lineup includes the PN Series with brake and the Z Series
with High Environmental Resistance (dust-tight, watertight).

High accuracy and interchangeability Absolute positioning accuracy

Interchangeable Motors and Driver Units can be randomly matched. 90 [arc-sec]
Increased positioning accuracy of 90 [arc-sec] and interchangeability
improve ease of use.

Intelligent Positioning controller function
is a standard feature
The EDC Driver Unit’s positioning controller function is provided as a
standard feature. In addition, an electronic gear function is built in for Compliant with UL Standards,
setting the pulse train position command. The EDC Megaterm software is CE mark, EU RoHS Directive
used to collect, edit, and monitor data.

Full consideration for people and
the environment

Compliance with international safety standards (UL Standards, CE mark)
assures worldwide applicability (PS/PN Series). The Megatorque Motor is
environment friendly and complies with the EU RoHS Directive.
