This marks a departure for Zongshen. As I said, until now the team has been racing with Agni motors, and doing very well against the competition. The switch to Yasa motors should give them more power and of course switch them from permanent magnet brushed DC to a proper AC motor.
Currently the team is racing with the two Agni powered machines they already have, and this new Yasa powered machine.
Going by the specs below, the team is using a YASA-750 motor which the company describes as so:
The YASA-750 has been designed as high torque direct drive motor for sport car and racing applications. The motor outputs a very high peak torque (750Nm) and a high continuous torque (400Nm) in a lightweight package (25kg).
The motor can deliver up to 100kW of peak power with a top speed of 2000 rpm (higher powers and speeds possible above 380V). The motors can deliver a high continuous power of >50kW (1800rpm and 300Nm continuous, for example).
