1 - OVERVIEW

The M32 flywheel components are as follows 
(numbers correspond to the callouts in Figure 1 on the 
preceding image):

Flywheel Housing (1):

 Vacuum vessel that houses 

the components numbered 2 through 9.

Passive Vacuum Pump (2):

 Canister of molecule-

adsorbing desiccants that maintain the appropriate 
vacuum environment within the Flywheel Housing 
(1).

Bearing Caps (3):

 Cover and provide access to the 

upper and lower Bearings (4). There is also a jack 
screw underneath the lower Bearing Cap that 
lowers the Flywheel Rotor (7) onto internal 
supports to protect the Bearings (4) from damage 
during shipping. You will remove the lower Bearing 
Cap and adjust this jack screw during installation.

Bearings (4): 

Support the Flywheel Rotor (7).

Electronics Enclosure (5):

 Houses a number of 

electronic components, including the electrical 
powertrain, instrumentation, communications, and 
control.

Offloader (6):

 Electromagnet that reduces loads on 

the Bearings (4) by providing a lifting force for the 
Flywheel (7).

Flywheel Rotor (7): 

Rotating mass that stores 

mechanical energy for conversion into electricity.

Motor/Generator (8):

 Converts electrical energy to 

mechanical energy when the Flywheel Rotor is 
charging, and vice-versa when the Flywheel Rotor 
is discharging. The Motor/Generator also contains 
the current-carrying conductors that route power 
to and from the Electronics Enclosure (5).

Feet (9):

 Support the Flywheel Housing (1) and 

other components.

Capsule (not shown):

 Encloses the M32 flywheel 

and other components within the excavated hole.

Capsule Lid (not shown):

 Covers the Capsule to 

prevent rain and debris from falling into the 
Capsule.
