EV Solutions
Drive components for electric two and three wheelers and light electric vehicles: belt final drives, hub motors, mid-drive units and traction CVT motors. The design problem here is instant torque from standstill and near-silent running that exposes every other noise. SES holds the range as an authorised JK Fenner distributor, covering product groups Belt drive systems, hub motors, mid drives, CVT motors; vehicle classes Two, three wheeler and light electric vehicles; drive forms Direct drive, geared and belt final drive; torque delivery Full torque from standstill. Executions include belt drive systems, hub motor systems, mid drive motor solutions, traction CVT motors. It is specified most often into electric scooters and motorcycles and electric three wheelers for passenger and cargo duty. Every part is genuine JK Fenner through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find EV Solutions in the parts of a plant where this particular duty actually occurs. In practice that means electric scooters and motorcycles, electric three wheelers for passenger and cargo duty, light electric utility and delivery vehicles, and equally electric cycles and pedal assist platforms, campus and intra-plant electric transport, retrofit and conversion programmes. What links them is the duty rather than the machine name — covers: Belt drives, hub motors, mid drives, CVT motors. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the JK Fenner range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Vehicle is a low speed, frequent stop delivery platform — A hub motor for simplicity, accepting the unsprung mass penalty. Where gradients and load are severe, a mid-drive making use of gearing will hold efficiency far better. Drive whine is being reported by riders on an otherwise silent vehicle — A belt final drive instead of chain or gear. With no engine noise to mask it, the mesh frequency of a gear train becomes the loudest thing on the vehicle. Regenerative braking is part of the control strategy — Confirm the drive path is rated for reverse torque. A component sized only for the drive direction sees loads it was never checked against every time the rider lifts off. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Specify the whole drive path together rather than buying a motor and matching a drive to it afterwards. On an electric vehicle the controller current limit, the gearing and the final drive rating are one decision, and splitting them is how prototypes end up torque-limited by their weakest link.
