Showroom Review Commercial Simulator NjMotion SV-2

I am going to present you the Motion Simulator NjMotion SV-2

The SV-2 is a commercial pre assembled motion simulator which is developed and sold by our member NjMotion - I call this one a RtD, a Ready to Drive simulator because it needs almost no DIY work to make it running, except installing and configuring SimTools.


SV-3 incl.- traction loss

The SV-2 is a interesting product because it is placed in the semi price range and therefore affordable for many users.

I am curious for testing it because the SV-2 has a few advantages compared to other (commercial) motion simulators:

Main Features (not tested,yet)

• 100 - 140mm travel adjustable
• 50 - 180mm/s speed adjustable
• 40Kg of force per actuator
• Potis for adjusting the speed and travel distance in real time while driving
• Very quiet, almost no noise

The SV-2 is using industrial Servo Motors which are created for high efficiency and accuracy so theoretically it should be running more accurate and faster than any wiper motors.

There is also a version called SV-3 with one more pivot and with traction loss.
I ordered the SV-2 because i am mainly driving with a VR headset and need to compensate the movements of the simulator from the oculus rift view. Doing this for two axis is hard enough so i first try to find out a drivable constellation with a 2 DOF setup. (Maybe i am able to create another axis in the future.)

Delivery time:

• Estimated delivery time is from 1-2 months

Order:

You can order the SV-2 and SV-3 via PM or Facebook

Prices (09.05.2017):

• SV-2 € 2000
• SV-3TL € 2800

Today the little box is going on its way:



I keep you posted when it arrives and i am able to have a first test run.

I did built my own SCN5 based simulator in 2012 or so and sold it a short time after finishing it. Journey was the goal Now it's time for me to let other guys do the job - much better and more professionally than i was ever able to do. In 4 days the sim will arrive.

The Simulator arrived today. Had a busy day with unpacking that beauty and carrying it to my top floor.

First impressions:

• Very well packed
• Heavy. I estimate 80kg
• Rock solid. Even Schwarzenegger could not bend the frame. It's a pleasure to look at the accurate welded joints.
• Very good looking and clean matt painting
• Absolutely no play anywhere. Nothing is moving and the complete construction is from very good quality.
• The total length of the frame can easily be adjusted as well as the height of the steering wheel mount and the angle of the foot pedal holder
• Had a first glance at the motors and amplifiers. These are indeed expensive industrial ones which are connected to a strong gearbox. I assume its a worm drive but i don't plan to disassemble the components
• The interface and power supply including amplifiers are build into the case which sits on top of the motor body.
• Only two cables, USB and power are going to the outside.

Now i am connecting the sim the first time to SimTools and do first testings.
So i will update this thread soon.

Hi guys,

i am very busy at the moment but i already created a first video with the simulator on track. My overall experience with the simulator so far is excellent. So let me summarize it for the moment:

The thing i really like is that the simulator is already prepared to be used as a full motion platform and not only as a seat mover which i am currently running. There are knurled-head screws which allows you to attach pedal and wheel holder to the moving base. The engine transmission unit is also more than strong enough to operate with the full body width. The frame is made of 40mm square tube which made to resist even the heaviest driver.

My first setup is far away from perfect. The seat is temporally attached by me with rests of my garden sheds. This results in in this cracking sounds which you can hear in the video. I will also mount it to a lower position which is more comfortable to reach the pedals. The simulator
itself is very silent and nearly unhearable. I will do another video later to proof this:



The track i am driving in the video is an Assetto Costa mod track (Hockenheimring). Unfortunately this is not a laser scanned track and it does not includes any surface road irregularities. So there is not much movement except the usual driving g forces. Driving the Nordschleife is the opposite and even the smallest bumps and road irregularities are noticeable with high resolution.

In the video i am driving the simulator with pots adjustments of speed: 45% and travel distance of 35%.
The best is that you can adjust these values just in time during the race so you can adapt the speed and travel perfectly to the car and track. Therefore you have two pots attached to the kill switch.

If you have any other question which i can answer just let me know.

Pots: speed: 45% and travel distance 35%

Hi @Coop

i was on a few business trips during the last weeks so i did not had time to drive the machine
For a good VR headset experience you definitely need a motion cancellation method. I am using a rift touchcontroller and the motion cancellation software mentioned here: https://www.xsimulator.net/community/threads/vr-motion-cancellation-time-to-test.10241/ This works very well and all the simulator movements are deducted from the headset movements without any noticeable delay. This give a

The NjMotion V2 and the Rift together delivers an astounding virtual reality experience and very realistic sensation as far as i can evaluate it with my non professional driving expertise When i find some time i will convert the simulator (for testing) into a full moving platform and compare it than with the current setup. I am curious to know which one feels more naturally. Videos will follow than

I've never driven a SimXperience simulator but i had a self build SCN5 based seatmover a few years ago.
My personal opinion is that the NjMotion is much more suitable if you have family members living with you in the same household. SCN5 systems are great from the motion aspect but they are extremely loud.

Servo based simulators like the NjMotion one pairs a very quiet simulator design with rapid and strong movements. The accuracy feels the same like using SCN5 actuators. My comparison is below:

SCN Actuators Pro

- Very accurate
- Fast Movements
- Easy to connect

SCN Actuators Contra

- You should not have neighbours or even a girlfriend - Yes, they are so loud

#################

Servo Pro

- Very accurate
- Fast Movements
- DC Motor cheap

Servo Motor Contra

- More affords to connect and program them
- Real servo motors as they are used by NjMotion are expensive as well


#################


DC Motor Pro

- Cheap

DC Motor Contra

- Much affords are needed to connect and program them
- Less accuracy
- Less speed

> the builder was able to fabricate some custom supports for my shifter and handbrake and I must say that he knows what he is doing while working with metal.

This was my first thought when i saw the welded frame the first time.

Feel free to post some videos and images into this thread as well. So we can collect the NjMotion stuff here in one place.
