Standard Motor OD 155mm

Product catalog summary

Overview: This technical guide focuses on selecting standard motors with a 155 mm stator outer diameter (OD). It highlights improvements in motor design, such as increased power density, enhanced heat dissipation, and cost-effectiveness due to the use of flat copper wire instead of round wire.

Key Specifications:

Slot Full Rate Increase: The use of flat copper wire increases the copper fill rate in the slot by over 25%, enhancing power density.
Heat Dissipation: The effective contact area between the flat copper wire and the stator core is increased, resulting in a 17.5% lower winding temperature rise compared to round wire motors.
Cost-Effectiveness: The motor diameter is reduced by 10%, and the axis length is reduced by 15%, leading to performance increases and weight decreases.

Motor Models and Performance: Detailed specifications are provided for various motor models, including rated power, minimum bus voltage, line current, frequency, rated torque, overload multiples, and peak speed. Performance data is given for continuous (S1) and peak (S2-30s) performance at different speeds (rpm) for motors with different stack stator lengths (60mm to 300mm).

Performance Data:

Continuous Performance (S1): Data includes continuous torque (Nm) and continuous power (kW) at various speeds (rpm).
Peak Performance (S2-30s): Data includes peak torque (Nm) and peak power (kW) at various speeds (rpm).

Additional Notes:

The actual overload capacity and peak speed of the motor depend on the user's usage time and voltage platform.

Motor Performance Overview: The document provides detailed specifications and performance data for motors with varying stack stator sizes and operational speeds. The data is organized by motor performance at different RPMs (3000, 3500, and 4000) and stack stator sizes (ranging from 60mm to 300mm).

Continuous Performance (S1): Continuous performance data is provided for each motor configuration, detailing the continuous torque (Nm) and continuous power (kW) at various speeds (rpm). The data shows how torque and power output change with increasing speed, highlighting the motor's efficiency and capability under continuous operation.

Peak Performance (S2-30s): Peak performance data is also provided, indicating the peak torque (Nm) and peak power (kW) achievable for short durations (30 seconds) at different speeds. This data is crucial for understanding the motor's capacity to handle short bursts of high demand.

Key Observations:

As the stack stator size increases, both continuous and peak performance metrics generally improve, indicating higher power and torque capabilities.
At higher RPMs, the continuous power output tends to stabilize, while peak power output shows significant increases, especially in larger stator sizes.
The document includes specific model numbers, rated power, minimum bus voltage, line current, frequency, rated torque, overload multiples, and peak speed for each motor configuration.

Recommendations: When selecting a motor, consider the specific operational requirements, including the need for continuous versus peak performance, and choose a motor configuration that aligns with the application's power and torque demands.

The stator of round wire motor The stator of flat wire motor Slot full rate increased： The conductor is flat copper wire. The copper full rate in the slot is increased by more than 25%, and the power density of the motor is increased. Better heat dissipation: The effective contact area between the flat copper wire and the stator core increases. The winding temperature rise is 17.5% lower than the round wire motor, and the heat dissipation is better. More cost-effective: The motor diameter is reduced by 10%, and the axis length (height) is reduced by 15%. Performance increases, weight decreases....
