FAQs

Depending on the version of the motor, the lead time may vary. As a general rule of thumb, for units that are standard configurations, the lead time for small volumes (1-5 units) is around 6-8 weeks. For bigger volumes or small customizations the lead time may change, please reach out to us at sales@alvaindustries.com or call us.

The SlimTorq™ motors are of the three-phase BLDC type & can be driven with most off-the-shelf controllers. The motors can be driven in trapezoidal, FOC, sinusoidal mode & with or without sensor feedback. Special considerations need to be taken regarding the switching frequency due to low inductance of the motors. Please read more under Choosing a Motor Drive section of the Product Catalog.

Due the inherent simplicity & flexibility our manufacturing technology FiberPrinting™ we can offer fully custom solutions for your application. Please contact us at sales@alvaindustries.com to learn more.

The motors can be configured perfectly to your application. There are many sizes to choose from and each size have many options that can be configured to match with you needs.

‍

Almost all the motor come in two main configurations: Lite and Max. Lite is the lightweight option and Max has been maximised in terms of motor constant and torque output.

‍

Each motor has multiple winding configurations to align with your required max-speed. The motors can be configured in Star(Y) and Delta(D), and in different number of series-turns. The cables exit orientation also come in two variants: axial and radial.

The motors can be equipped with temperature sensors and different wire gauges.

To understand how to configure your product please see the Configured To Your Needs section of the Product Catalog and to simplify the process check out our Product Selector.

‍

Please contact us at sales@alvaindustries.com if there isn’t a configuration that meets your needs. Our FiberPrinting™ technology allows us to quickly develop custom motors according to your requirements.

‍

There are three general concepts for mechanical integration of the frameless motors

‍

1. Clamping
2. Adhesion
3. Interference fit

‍

All three has their inherent advantages & considerations, please read more under the Mechanical Integration section of the Product Catalog.

The easiest way to select correct motor for your application is to use our Product Selector. Insert you requirements in the Product Selector and it will find precisely the right motor for you. It will also allow you to fully configure the motor and order it. We are happy to help if you desire personal assistance to select the right motor, just contact us on sales@alvaindustries.com.

No. Alva’s manufacturing methods, lead by the FiberPrinting™ technology, are comparable in cost and price with motors with similar characteristics (thin, light, cogging free slotless frameless motors).

‍

Most of the SlimTorq™ motors can be ordered with a temperature sensor as an optional feature. Each specific product page in the Product Catalog specifies if it’s available with temperature sensor option under the Temperature Option row. Please the see Ordering Alva Motors section in the Product Catalog to see how you configure your product with a temperature sensor.

‍

Typically yes, slotless motors tend to be more expensive than slotted motors. The reason lies on the manufacturing methods required to manufacture the windings and the need for more powerful and heavier magnets. However FiberPrinting™ and Alva’s methods of manufacturing our Halbach Array rotors, can be quite competitive with slotted solutions.

‍

The GearTorq™ motors are brushless motors, they are therefore inherently not exposed to any mechanical wear assuming a well designed mechanical assembly. The Litz Wire of the stator windings are isolated with of a P180 enamel according to IEC 60172, with a rated lifetime of 20,000 hrs at a continuous temperature of 180 °C.

‍

As long as the motors doesn’t exceed their maximum rated temperature of 140°C, the motors will have next to unlimited life-time.

With a large inner-diameter and low-speed dependant losses, the GearTorq™ motors are highly suitable to be combined with gearboxes for torque demanding applications. They can be combined with all the typical type of gearboxes for precision applications such as planetary-, worm-, strain wave-, bevel- and cycloidal-gearbox.

The continuous torque and speed values in the product guide are based on the assumption that motors are  mounted in a small housing and with some airflow passing over the housing. To understand how the motor will perform in your application please insert your requirements and select the correct cooling conditions in our Product Selector. Or contact us at sales@alvaindustries.com& we can support you with a detailed thermal & performance study.

All the GearTorq™ motors are rated with a maximum voltage level of 72V. Higher voltage ratings will be available in the future. Please contact sales@alvaindustries.com if your application require a higher voltage rating.

Alva’s FiberPrinting™ manufacturing technology for slottless stators & proprietary manufacturing method of Halbach array rotors, allow for production cost that can be quite competitive to even manufacturing methods of slotted motors, enabling also competitive pricing. On the other hand, slotless motors from other manufacturers tend to be more expensive than slotted motors due to the larger magnets & legacy manufacturing methods.
