Stall current rating of T200 thrusters?

Hi @nitesh,

Please see this post for current draw information:

Transmission design motor info

Hi @lunarElipse, We don’t actually have this information available, as we don’t have any experimental torque/speed data at this time. However, I can provide some rough charts of what we would expect based on a simulation. These are estimates, but they should be reasonably accurate assuming a 12 V supply with an ideal ESC at full throttle and a 1 m long 18 AWG cable from it to the motor. These numbers may vary depending on the exact timing and commutation behavior of the ESC used, but do match u…

“Stall current” is a bit of a misnomer is brushless sensorless motors like ours. As feedback is required to commutate the motor, its not even possible to run below a certain RPM, and thus current will not be drawn in the traditional sense when stalled. This behavior is mostly determined by the ESC rather than the motor. With the Basic ESC, the T200 will stop running below about 300 RPM. If stalled, the ESC will detect this and stop running the motor until reinitialized with a 1500µs neutral signal. If still stalled the process will repeat, otherwise it will resume running normally. As previously noted, the stall behavior and recovery is dependent on the ESC used.

If the sediment you are running in has ferrous particles, you will need to periodically open the thruster and remove this buildup from the rotor magnets manually.
