SMC have introduced their new Totemic brushless stock motors. Development focus has been on producing a solid platform that does not fade and still produces maximum output thanks to an optimised coil resistance. The Totemic family of motors include 13.5, 17.5 and 21.5 turn motors, each comes fitted with a 12.5mm rotor with the strongest magnets available. 12.3mm rotors are available for those looking for a bit more RPM. All motors come with pure copper solder tabs and collector ring, each gold plated for the best resistance and minimum oxidization. The motors are ROAR approved and available now.
Coming from Fenix Racing are several new parts such as a gear differential for 1/12th scale pan cars, a set of titanium front axles for the Xray X1 and a 17.5T brushless stock motor. Starting with the gear differential, the unit is based on Fenix’s poplar 1/10th gear diff and it features a Grade 5 titanium axle, ABEC 5 class 1/4×3/8×1/8 ball bearings and it utilises a 84T 64 pitch main gear. The prototype already showed some great performance with a 3rd place in the highly competitive 10.5T class at the recent Masters of Foam race in the hands of Jaques Libar.
Hobbywing have introduced their new XeRun 3652 and 3660 SD G2 sensored brushless motors. Equipped with a built-in chip that lets Hobbywing XR8 series brushless controllers recognise the motor, the system will provide improved performance and smoother control in sensored mode. The motor is housed in a machined aluminium case with heatsink design for optimised heat dissipation and the low cogging design with 4-pole/8-magnet setup reduces cogging for improved driving feel at lower speeds. This is further helped by a special hall sensor system that ensures clean and “error free” hall sensor output signals. On top of this the motors feature an adjustable mechanical timing in a 20 to 40 degree range and they use silicone O-ring seals for sensor port protection. The shorter 3652 motor is available as 3100kv to 6100kv variant with 3.175mm or 5.0mm output shaft while the longer 3660 variant comes in 3200kv to 4300kv specification, exclusively with 5mm output shaft.
Coming from Reedy is the 540-SL4 sensorless brushless motor for ready-to-run vehicles. Due to its 4-pole configuration, the motor offers high power, efficiency and reliability as it is needed for demanding RTR applications. The 3300kV rating provides plenty of speed with 2S LiPo batteries but installing a 3S LiPo battery makes for even higher speeds. At the same time does a high-strength rotor provide plenty of torque and resists overheating better than 2-pole alternatives. The motor comes pre-wired with flexible silicone wires that ease wire routing in tight spaces and work in conjunction with 3.5mm bullet connectors to reduce power-robbing resistance and heat. The package is rounded out by triple insulated windings, a hardened steel shaft, and oversized ball bearings.
Coming from Yokomo are the new Zero 2 series sport-level brushless motors. Featuring a newly designed and black anodised aluminium can the motors are available in a range of windings including 6.5T and 8.5T modified as well as 10.5T to 30.5T stock variants. The fully enclosed design without cooling openings result in a motor that requires very little maintenance even when operated in dusty conditions and the motors come pre-wired with bullet-type connectors, compatible with many entry and sport-level brushless speed controllers.
Maclan Racing have introduced the MRR Team Edition electric brushless motors. Based on the popular MRR platform the Team Edition utilises Japanese made steel stator material for the short stack style rotors. Custom-made copper wire also has a higher temperature threshold along with maximum diameter allowed by ROAR regulations. Overall the Team Edition has an average four percent lower internal resistance compared to the standard MRR series motors. Also part of the TE package are all-new hall sensors that are more accurate while offering a much higher speed polling rate which will provide quicker throttle response with higher top speeds. The hand-built motors will become available by late November.
Castle Creations have introduced a range of sensored brushless motors. Known for their popular sensorless “basher” motors, Castle now also steps into the highly competitive sensor game with several different sizes of motors. The range starts with the 41.1mm diameter 15xx-series motors such as the 1515 2200kv, 1512 2650kv and 1512 1800kv variant with the 1515 targeting towards 1/8th buggies, truggies and 1/10th monster trucks while the 1512-series is best suited for 1/8th on-road and off-road vehicles as well as 1/10th 4WD SC trucks.
Team Orion have released first information on their forthcoming Vortex Ultimate Stock brushless motors. Aimed at the ultra-competitive blinky stock racing the 540-size motors are developed in the USA from the ground up. They features a new high-power stator design, utilise low resistance copper windings and are built using a 3-piece low centre of gravity can design. The motors also feature a precision-balanced neodymium rotor, heavy duty pre-shaped solder tabs, widely adjustable timing and they are HV battery compatible. They are designed to meed IFMAR, ROAR and EFRA rules and they will soon be available in a 13.5T and 17.5T variant.
