SP180-B1

It is a power system with continuous output power of 5kW, including 5kW PMSM motor and 5kW FOC motor controller. The product can provide two rated voltage operating modes, 48V and 60V(Rated voltage expansion :48V/60V/72V/84V) which can be automatically adjusted according to the battery system. Due to the excellent heat dissipation structure design and multi-level temperature control strategy, the power system is able to make continuous stable large-scale power output under natural air cooling conditions, which has been applied to the SUR-RON light bee model with mass production.

SP180-C1

This power system include two configurations: rated 60V low-voltage with 8kW air-cooling system or with a 10kW water-cooling system. The peak output power can reach maximum 18kW, peak torque can reach 66 N.m. The system include a PMSM motor( SMP180-08 series), a gearbox(optional) and a FOC controller( SD08 series). By matching with high-speed motor with gearbox, this power system can achieved both high power density and high torque output, the mechanical characteristic curve of the power system is further optimized. The system shows high torque at low speed and full power at high speed. With CAN communication function, the vehicle can be fully intelligent.

SUR-RON Motor Controller

The product adopts advanced vector control algorithm (FOC), excellent heat dissipation structure design and EMC circuit design, enabling it to own high reliability and environmental friendliness while achieving high performance. In the meantime, the product enjoys quick dynamic response, large low-frequency torque and an intelligent control system with the ability to better understand users' operation purposes. The products have various functions such as energy recovery, high-speed field weakening and traction control.

SD05

The product adopts advanced vector control algorithm (FOC), excellent heat dissipation structure design and EMC circuit design, enabling it to own high reliability and environmental friendliness while achieving high performance. In the meantime, the product enjoys quick dynamic response, large low-frequency torque and an intelligent control system with the ability to better understand users' operation purposes. The products have various functions such as energy recovery, high-speed field weakening and traction control.

SD08

The vector controller with rated 8kW, and it adopt 485/CAN communication mode (according to user selection, CAN communication protocol is recommended.). It has many high performance functions such as electric energy recovery, high speed and weak magnetism and traction control, and it has abundant electrical interfaces. The core devices of it adopt the automobile-grade kernel chip, based on the high protection standard of IP67 and the full potting sealing structure, to ensure the high reliability of the product.

SUR-RON Motor

High power permanent magnet synchronous motor is excellent products which is based on electromagnetic simulation and magnetic circuit structure optimization design and combines with rich experience in engineering design. With high performance permanent magnet element, solid material, exquisite technology, the motor has high power density, high temperature resistance grade, high motor speed, wide efficient platform and large output torque.

SMP180-05

The 5kW rated sinewave controller, adopts 485/CAN communication protocol, has multiple safety& security protection setting and various functional port, and its written in a control system based on the professional riding strategy, this unique feature is only for high-performance electric motorcycle. Full potting structure, maximum IP67 protection level, and long-term reliability testing ensure the high-quality of the product.

SMP180-08

Permanent magnet synchronous motor based on natural air cooling, has mature radial magnetic field design, and motor power density is higher. The permanent magnet material of high performance grade and standard guarantee working reliably in a higher temperature environment. The high quality of material, and the higher coil space factor make the motor output more torque. The unitary modular position sensor can make the motor more anti-interference and more accurate and reliable control. With the series design of 8kw motor, it makes the production process and supply match more consistent, and the system quality guarantee is more reliable.
