New projection screen motor for DIY multiformat projection screens

When you want to make a your own DIY electric multiformat projection screen, you can use a dual tube system.

The fabric in the front would work as the mask.

In the video below, you can see how that works:

The difficulty is in controlling the motors at the same time, so you get the masking fabric perfectly in sync with the projection fabric.

Even a minimal delay when using two motors results in the black borders not wrapping around the fabric perfectly.

Which is why the new Era Zero MVS by Nice is a great solution

The new Era Zero MVS tubular motor by Nice – why it matters

Tubular motors rarely are developed with projection screens in mind.

That’s because projection screens are a small market for tubular motor manufacturers compared to the marker of awnings and roller shutters.

The result is that innovative features that benefit projection screens are always lacking.

This motor is an exception and was developed specifically for multi format projection screens.

This means multiple motors will work in perfect sync, resulting in a black border that perfectly wraps around the projected image.

For which sort of multiformat projection screen can you use this motor?

As far as I am aware, the motor is only available in a 220 V version, which means that if you want to use it in the US for example, you’ll need a power converter.

The motor has an integrated radio receiver, which allows it to be remote controlled.

The “way” control unit is the most useful, as it allows you to pre-set whichever aspect ratio you want to use.

Keep in mind that the multi format screen you can build with this motor is a Constant Image Width (CIW) projection screen, as the mask will be created by up and down movement of both of the fabrics.

The fact that the motor has a built-in receiver makes it incompatible with other brands that use radio signals.

However, the motor has 6 wires in stead of 3, because 3 of the cqables are data cables which you can use to hook it up to a control system.

Versions of the MVS motor

There are 2 versions of the MVS motor: a quiet one, called the Era Zero MVS and the Era Mat MVS.

The difference is in the noise level. The Zero has a reduced noise level compared to other motors and compared to the standard Nice motors.

It’s 6 dbA less, which is quite significant.

(Keep in mind though that the build quality of your screen matters big time when measuring final noise levels, as it can either amplify or reduce sound levels of the motor)

Full specifications of the new motors

Below are the full range of benefits and the specifications of both motors.

Nice Era Zero MVS details

  • Reliable in all situations: available in the following 4 Nm, 8 Nm.
  • The quietest of them all: noise is reduced by over 6 dbA with respect to standard Nice motors.
  • Ideal in environments where minimal noise levels must be maintained.
  • Optimum power and low noise performance thanks to the new motor system, new internal geometry and use of exclusive materials.
  • Maximum precision: the encoder technology guarantees millimetric precision, reliability and stable set values over time.
  • Complete and intuitive programming thanks to feedback from movement of the projection screen
  • Convenient remote control of limit switch positions by transmitter or with the O-View TT and TTP external programming units.
  • Compact: overall length just 466 mm.
  • A number of motors can be operated synchronously at the same time to create different projection screen formats.
  • Simple to install thanks to the practical mounting and ease of adjustment.
  • Low consumption in stand-by.

Conclusion

If you are looking to build a high-end multi-format projection screen, this is definitely the motor to go for.

Real projection screen motors are rare and I would personally love to see this initiative of Nice become a success.

    I love those motors. I have a couple of them in my house and they are very simple to set-up and noise level it is good.
    The previous motors was Somfy but when they started and stopped it make clack – clack …. terrible
    Nice well done …
