Accessories

Electric motor accessories are everything you need to start, mount and control a drive. At Stojan you will find pulleys, couplings, frequency inverters, start capacitors, motor feet, flanges and spare parts — over 200 items available from stock, dispatched within 24 hours from our warehouse in Poland.

What will you find in the accessories category?

Power transmission — pulleys and couplings

Pulleys (taper lock, SPA/SPZ/SPB) and V-belts transmit torque from the motor shaft to the driven machine while allowing you to select the transmission ratio. Jaw, flexible and sleeve couplings connect shafts coaxially, compensating for minor misalignment and damping vibration. Selection depends on power, speed and shaft diameter.

Control — frequency inverters

A frequency inverter (VFD) allows smooth speed control of a three-phase motor, soft acceleration and braking, and running a 3-phase motor from a 230 V single-phase socket. It is an essential accessory for pumps, fans and conveyors where output needs to be adjusted.

Starting single-phase motors — capacitors

Start and run capacitors are essential in 230 V single-phase motors. A worn capacitor is the most common reason a motor fails to start — it "hums" but does not turn. We match the capacitance (µF) and voltage to the specific model.

Mounting — feet, flanges, parts

Motor feet (conversion to B3 mounting), B5/B14 flanges, fan cowls, cooling fans, bearings and seals — everything you need to install and service a drive.
