ReGen Drives

The smart choice

Otis brings the advantages of regenerative-drive technology to 

low- and mid-rise residential and commercial buildings. The compact 

modular design makes ReGenTM drives ideal for application on 

Gen2TM systems.

key benefits

A ‘green’ solution

As the product of choice for “green” 

building initiatives, ReGenTM drives 

deliver substantial energy savings 

while helping to meet or exceed 

established worldwide standards. 

Generating energy savings

In a typical non-regenerative drive, 

energy is dissipated as heat in a set 

of resistors when braking occurs, 

resulting in reduced efficiency 

and creating additional waste-heat 

loads in the building. ReGen 

drives feed this energy back into 

the building’s internal electrical 

grid where it can be used by other 

loads or users connected to the 

same network.

ReGen drives reduce energy 

usage by up to 75 percent 

compared to non-regenerative 

drives. The drives are so efficient 

that their power factor is close 

to unity. 

Minimizing harmonic distortion 

ReGen drives produce “clean 

power” — resulting in less pollution of the building’s electrical 

power system and helping to protect sensitive building equipment.

The drives minimize distortion of the incoming sinusoidal 

waveform line current, making 

Total Harmonic Distortion (THD) 

at nominal load typically equal to 

or below 5 percent, versus more 

than 80 percent in non-regenerative drives.

Reducing Radio Frequency 

Interference (RFI)

ReGen drives substantially minimize 

RFI, or Electromagnetic Interference 

(EMI) — virtually eliminating disruptions to other building electronic 

systems and ensuring compliance 

with strict regulations around 

the world.

Significant annual savings

ReGen drives lower overall building 

operating costs, delivering significant 

annual savings to building owners 

and tenants year-after-year during 

the life of the elevator.

The drives help reduce the two 

key factors that influence energy 

costs, peak power demand and 

energy consumption. As a result, 

both the fixed costs based on peak 

power demand (kilovolt amperes or 

kVA) and variable costs based on 

energy consumption (kilowatt-hours 

or kWh) decrease.

Electrical power is generated 

when the elevator travels up with 

a light load, travels down with a 

heavy load and during the elevator 

system deceleration. In effect, a 

fully loaded, descending elevator 

can now provide a significant portion 

of the power for an adjacent 

ascending elevator.

The amount of energy savings 

due to regeneration depends on 

various system parameters and 

configurations such as car load, 

speed, length of run, traffic pattern 

and system efficiency.

Modeling and simulation results 

show that ReGen drives use 

substantially less energy than nonregenerative drives for equivalent 

elevator motion. (See energy savings 

example on back page.)

As a “green,” cost effective option 

for the Gen2 system, ReGen drives 

are the smart choice for your next 

low- or mid-rise installation.
