1 AC parameter download High speed air-cooled The low inertia, high overload with high speed gradient air-cooled ensures high dynamic response to perform steady and dynamic tests for automotive components. High power, high torque High-torque s cover medium and heavy-duty traditional, hybrid or electric bus and commercial vehicle testing as well as powertrain and transmission transient tests. Pure water-cooled Water-cooled s have very low noise levels and heat source control which are suitable for hybrid or electric vehicle powertrains, transmissions testing with noise requirement. Water-cooled with small blower Water-cooled with small blower or air-cooled with heat exchange ensures effective cooling. More compact design, higher power and torque for higher dynamic performance.

2 PM synchronous drive Powertrain test needs small and low inertia permanent magnet synchronous to avoid interference with transmission to simulate engine torque pulse. Electric powertrain high speed In particular, hybrid or electric vehicle motor testing requires a low-inertia permanent magnet synchronous that requires more than 20,000 rpm. Up to 120,000rpm ultra-high speed Ultra-high-speed with air bearing or maglev bearing for automotive, aerospace and scientific testings. Performance can be customized. Megawatt water-cooled The megawatt water-cooled or with mix cooling reduces noise levels, ensuring effective cooling of the windings and rotors and reducing vibration. Dyno Equip can meet the customer specific requirements of the motor and with non-standard design and different cooling methods. The customer stringent requirements on power, torque, noise, size and moment of inertia can be achieved.

3 Power and torque curves The figure below shows the typical AC power curves (yellow solid line for continuous operation and yellow dotted line for short time overload) and torque curves (green solid line for continuous operation and green dotted line for short time overload). Usually the short time overload defines as one minute overload within ten minutes. The overload percentage is 120%. The overload time and percentage can be revised according to the motor design margin. The torque is constant when the AC is in the range from zero speed to the rated speed. Between the rated speed and the maximum speed, the torque value decreases with increasing speed. The constant power speed range in below figure since the rated speed to maximum speed. In some cases, in order to effectively suppress the maximum current for reducing inverter cost, the constant power speed range will be lower than the maximum speed value. 600 Overload torque (short time) (continuous operation) Overload power (short time) Rated power (continuous operation) SPEED [RPM] Maximum speed Torque - S1 (Nm) Torque - S6 (Nm) Power - S1 (kw) Power - S6 (kw)
