Wiring and operation

Use a DC supply matching the selected voltage. Never connect the motor directly to household AC. Reverse rotation by swapping the motor leads or using a compatible reversing controller. A suitable PWM controller can adjust speed; lowering speed may reduce available torque. Avoid overload and stalled operation.

Supplier data notes

Dimensions and weights are approximate. Power, current, noise, temperature and continuous-duty figures are supplier-listed; measurement conditions are not fully specified. Where power and current do not agree, confirm actual supply demand rather than assuming the listed wattage is verified electrical input power. Stall torque is a limit, not a continuous operating rating. No waterproof rating is supplied.

Package contents

One motor in the selected configuration, plus only the accessories named in the selected Package option. Supply plug type and complete controller ratings are not specified; confirm compatibility for your installation.
