Motor Test Capacity Calculator
Motor test capacity determines whether hub motors, mid-drives, controllers, or wheel-motor assemblies can clear end-of-line electrical and torque checks before final assembly. Operations and quality teams use this result to balance dyno benches, firmware stations, operators, and incoming motor lots against the vehicle build plan.
What this calculator does
- Estimate accepted e-bike or scooter motor test output from motors tested per cycle, available cycles, station uptime, and first-pass test yield.
- an e-bike or scooter assembly line needs to confirm motor test capacity before committing a daily or weekly production schedule
- Returns estimated accepted motors or drive assemblies available after test uptime and first-pass yield losses.
Formula used
- Gross motor test slots = motors tested per cycle × available motor test cycles
- Accepted motor test capacity = gross motor test slots × motor test station uptime × motor first-pass test yield
Inputs explained
- Motors tested per cycle: Use the number of hub motors, mid-drives, controllers, or wheel-motor assemblies completed per test cycle.
- Available motor test cycles: Use planned cycles from dyno benches, electrical testers, burn-in rigs, or EOL test stations in the period.
- Motor test station uptime: Account for tester availability after fixture changes, calibration, software issues, maintenance, and operator coverage.
- Motor first-pass test yield: Use the share expected to pass torque, current draw, hall sensor, controller, noise, or communication tests first time.
How to use the result
- Use it for motor bench staffing, fixture planning, controller firmware release timing, and final assembly schedule checks.
- It does not separate failure modes such as torque, noise, current draw, communication, or firmware mismatch; review test logs for root cause.
Common questions
- Can I use this for controller testing? Yes, if output per cycle and yield are based on controller test slots instead of complete motor assemblies.
- Should re-tested motors count? Include only first-pass accepted motors in yield. Re-test recovery should be planned separately if it consumes capacity.
- What if several testers have different cycle times? Run separate scenarios by tester family or convert them into equivalent cycles for a rough combined estimate.
- How can I use the result? Use it to decide whether motor test is the bottleneck and whether to add fixtures, operators, shifts, or pre-test screening.
