Product Description

The Coreless Motor of CJAC adopt diamond shaped windings which have a structure similar to a "saddle" and are also known as saddle shaped windings. This winding has better motor characteristic curves and can improve performance by more than 30% under the same size. winding has better motor characteristic curves and can improve performance by more than 30% under the same size. The Coreless Motor of CJAC have three The Coreless Motor of CJAC have three major characteristics: high power density fast response and smooth operation. Under the same volume the output power and torque are high the winding size is small the performance is good there is no need to change the motor size. Under the same volume the output power and torque are high the winding size is small the performance is good there is no generation of eddy currents and hysteresis losses and the operation is more efficient. In terms of motor In terms of motor response it starts or brakes quickly responds extremely quickly and has a mechanical time constant of 10-28 milliseconds. The motor runs stably with The motor runs stably with speed fluctuations within 2%. Our company can support customised motor needs of customers and can also integrate multiple modules such as planetary Our company can support customised motor needs of customers and can also integrate multiple modules such as planetary gear reducers brakes encoders and drive boards to form a complete integrated solution. The product series can be divided into six major series: standard Coreless Motor EC series high torque Coreless Motor ECT series high-speed Coreless Motor ECS series frameless motor FL series slotted motor ECI series and planetary reducer GP series meeting various application scenarios. Currently it is widely used in automation medical equipment robotics dexterous Currently it is widely used in automation medical equipment robotics dexterous hands aerospace and other fields.
