Something interesting is cooking in PML. Thanks to @phreakv6 that I had noticed this in their website. I will try to evaluate the products that are exciting me the most.
BLDC Motors
Source : Rotor & Stator Assemblies for BLDC Motors – Permanent Magnets Ltd
The specifications for the BLDC motors are very well defined. The project seems like it is in advanced stage with all the simulations and specifications displayed. The BLDC motor is also developed for a very niche application as we can see from the specifications. My hunch would be that PML has concrete requirement for a 2W OEM for development / manufacturing of BLDC motors.
Compared to a BLDC used in fans, they are more complex and we would need a Motor control unit ( MCU ) to control the phases. These components will need precise calibration so that the user does not feel jerks.
Please note this BLDC motor is not a hub motor which the current i-cube uses, the stator is the outer ring and the rotor is the inner ring (simply put: the inner ring rotates and the outer ring stays static)
Relays
They have also come out with mechanical relays. Currently there are not much info on it and it does not seem like an automotive relay component. However, every EV will have a relay (also called as contactor, switches) which will disconnect the Battery from the rest of the powertrain. I would not be surprised if they come out with mechanical relays for automotive application soon.
Shunt Sensor Module
I think most of us know how important is a shunt sensor in the context of an EV. I see that the company has a direction.
Speed Sensing
This is used to understand the speed of the vehicle. They are used in many places in a vehicle ( crank, wheels. gearbox etc. ) . In the context of 4 wheeler EV, I guess the most appropriate location will be in the 4 wheels if the vehicle has active safety enabled (anti skid, ESP etc.). Also they might be used in the out put shaft of the motor as a monitoring device. This item is also EV agnostic in my opinion
disc: Not invested. discovered this story late and currently tracking.
