Business & Core Strength

R&D powers our business and is fundamental to Lento’s underlying enterprise spirit that has helped us deliver quality, world class innovations and change the landscape of power electronics in the country. 

Design and develop smart, rugged and highly reliable products that offer the best price to performance ratio in the class. This core philosophy has helped us create some unusual, advanced power electronic devices, inverters, UPS, solar and LED lightings products that will create a new dimension in this field. 

We seamlessly integrate research & development, quality and delivery. Research by itself does not achieve much but research that brings products to markets and fulfills requirements is what makes a vital difference and Lento’s focus on applied research does just that. 

Anticipate the future and deliver products that are cost efficient and meet user requirements, giving them best returns on investments. 

Manufacturing is supported by extensive service and maintenance with a division created specifically to handle this important task that is so essential for customer satisfaction. 

Plough back profits into research and development of products as well as betterment of staff and the community in a holistic approach to business. 

Listen to feedback from users as an important contributory element to improvement of our products and our way of working.


Tomorrow’s technology, here, today, adapted for Indian conditions, Indian users and Indian budgets. This is how we work and this has resulted in our being the first to introduce digital signal processing based inverters and UPS. We offer pure Sine wave inverters in contrast to quasi sine wave or modified square wave inverters commonly available. A feather in our hat is the ALBS technology providing 3 phase inverter power for lifts and other equipments.

BLDC Motor





BLDC motors are more versatile, mainly because of their savvy in the speed and torque departments. They also come in compact packages, making them viable for a variety of compact designs. Typical apps include, HVAC and refrigeration, industrial and manufacturing systems, and direct-drive turntables.

Another advantage of a BLDC motor is that it can be made smaller and lighter than a brush type with the same power output, making the former suitable for applications where space is tight.

Because a BLDC motor dispenses with the brushes – instead employing an “electronic commutator" – the motor’s reliability and efficiency is improved by eliminating this source of wear and power loss. In addition, BLDC motors boast a number of other advantages over brush DC motors and induction motors, including better speed versus torque characteristics; faster dynamic response; noiseless operation; and higher speed ranges.

Traditionally, ferrite magnets were used to make the permanent magnets, while these magnets are more expensive, they generate greater flux density, allowing the rotor to be made smaller for a given torque. The use of these powerful magnets is a key reason why BLDC motors deliver higher power than a brush-type DC motor of the same size.

Moreover, the ratio of torque delivered relatively to the motor’s size is higher, making it a good choice for applications such as washing machines and EVs, where high power is needed but compactness and lightness are critical factors.
