Operator command
Defines intended direction and assist request.

POWER ASSIST SYSTEM
Force, torque, traction, speed, runtime and powered-wheel system integration.
A Power Assist System reduces operator propulsion effort while leaving navigation with the operator. The whole route becomes the design input.

Quick answer
A Power Assist System adds propulsion to an operator-guided cart.
The caster system still supports and steers the equipment. A motorized wheel contributes driving force so the operator does not have to provide the entire propulsion demand.
From operator input to useful assist force
Drive control
Converts the request into controlled motor output.
Wheel–floor interface
Limits how much useful force reaches the route.
Equipment response
Must be verified with the complete cart and duty cycle.
System architecture, safety controls and performance limits vary by product configuration and application.

A Power Assist System adds propulsion; casters still support and steer.

The powered wheel is one part of the mobility system. Wheel layout, caster geometry, braking, controls, floor condition and equipment stability still require equipment-level validation.
Design inputs
What determines required assist force?
Rolling
Wheel, bearing, alignment and floor losses
Slope
Gravity component along the route
Acceleration
Force required to change speed
Traction
Usable force at the wheel–floor interface
Duty cycle
Operating and recovery pattern
Estimate force and wheel torque with visible assumptions.
Start with mass, route, rolling-resistance assumption, acceleration and powered-wheel geometry. Then validate the complete system.

Questions, principles and design decisions
01
calculation
↗02PAS Battery Runtime Explained
Battery runtime is estimated from usable watt-hours divided by average power, then verified against route and duty-cycle testing.
explanation
↗03How Does a Motorized Caster Work?
A motorized caster converts electrical energy into controlled wheel torque while supporting or sharing the equipment load.
calculation
↗04How Much Weight Can a Powered Assist Wheel Move?
Movable mass cannot be determined from one rating because route resistance, slope, traction, acceleration and duty cycle set the requirement.
selection
↗05How to Select a Powered Wheel for a Cart
Select a powered wheel from route force, traction, duty cycle, controls, packaging and complete-cart validation requirements.
comparison
↗06Powered Caster vs AGV or AMR
Powered assist supports an operator-guided cart, while AGV and AMR systems add autonomous or infrastructure-guided movement.
comparison
↗07Powered Caster vs Electric Tug
A powered caster is integrated into equipment, while an electric tug is typically a separate vehicle coupled to one or more carts.
calculation
↗08Torque vs Load for Powered Wheels
Required wheel torque follows tractive force and wheel radius, while load influences rolling, slope and acceleration forces.
explanation
↗09Traction and Wheel Grip in Powered Assist Systems
Usable drive force is limited by wheel–floor friction and the normal load carried by each powered wheel.
definition
↗What Is a Powered Assist System?
A Powered Assist System adds controlled drive force to a cart or trolley while the operator retains guidance and supervision.
